It's technically possible but very uncommon, and using it on an active registration will raise some eyebrows at the registry. I'd almost forgotten it was an option at all.
Quite interesting, but aren't there restrictions on what circumstances they're allowed to delete domains? This section of the doc doesn't seem to speak to that, or maybe it's another doc entirely.
When a domain expires it’s automatically renewed at the registry in the case of gTLD’s.
A registrant then has 30-44 days (depending on the registrar) to “renew” but in fact the domain has already renewed so in what happens is the registrar deletes the domain in the case where they don’t have that affirmative action.
It does apply here. A domain does not need to be expired, a delete can be sent any time it’s active. The only prohibition is if the domain has “clientDeleteProhibited” status which the registrar can remove.
That's possible, but I'm _pretty_ sure that's not how it works, there are restrictions on what circumstances registrars are allowed to do various actions too.
