There was a similar problem in Sweden. In the old system a person could first seek asylum, get denied, then seek a work visa, get denied, then seek a student visa, get denied and then repeat the process since now enough years has passed. People could also simply go underground for a period of time and then restart the process.
Two law changes was added last year to prevent this. First, any decision remains in force indefinite as long the person remains in the country. The second is that all applications will be running simultaneous and the final decision is given at the same time, with no option to change application afterward if the result returned negative.
The system has some drawbacks, especially if the applicant apply for the wrong thing and don't change it until the decision has been reached, but it removes stalling and delaying tactics.

Yes but that still means communicating with the institutions and having some sort of legal status. What is en masse happening in the US and to a lesser extent was (or is, not sure, but see for example the Windrush scandal) happening in the UK is that people legally enter the country and have for a time legal standing to reside there, but that lapses, laws change etc., and just nobody cares deeply enough to solve the situation one way or another? And then decades pass and bad things start to happen. But all of this was entirely avoidable and I don't mean just 'not voting for Trump' avoidable, but in a systematic manner.
We could compare that to the situation in Spain where there is a group of illegal migrant workers who are exploited as cheap work force. Now they are given a chance to legalise their status but that too is happening after decades of neglect. Of course there are similar groups in other countries.
The Windrush situation is a bit different - the people involved were British Subjects, and didn't need any documentation when they arrived in the UK.
The only thing that changed was the introduction of the "hostile environment" policy in 2012, meaning that everyone (including full UK citizens) must now prove that they have permission to be in the country before getting a job, renting a home, getting a bank account, etc.
The Windrush generation always had that permission, and continued to have it - what they didn't have was the documentation to prove it. And, to make matters worse, the Home Office had disposed of their arrival records so in many cases it became all but impossible for them to get it.
(I know this is a minor quibble, but I think it's worth pointing out that the people affected shouldn't have needed to regularise their situation, because it was never irregular in the first place!)

This is what I don't agree with and exactly why I mentioned Windrush as an example. The situation was irregular because while they were legally entitled to stay, they didn't have a simple way to prove it. And once they needed that, it became an issue.
Now I assume most of them regularised their situation and some didn't and since the state knew enough about them to try to deport them, it should have fixed their status in the first place by issuing them the needed documents. But it didn't! And that was my original point - the state neglected their situation for decades, let them adapt to changing legislative environment on their own (or not), only to swing the axe (wrongly) without warning. If they were issued a citizen ID long ago none of that could ever happen.

The term we should be using here is human trafficking. It is a extremely common practice in construction and farming. As a police officer said here in Sweden in a news article, if they went to a single major construction site the yearly budget for human trafficking violations would be used up for that site alone. It is an open secret that construction sites has a tier based system for workers, where the most illegal workers (and there are different degrees to that) get the most dangerous assignments, least amount of safety equipment, longest hours, and with the lowest pay.
A lot of the calculation on the cost of reduced immigration get based on the resulting increase in costs to construction and farming. It is quite insane how much of the economy is based on exploiting people.
