The GP sounds exactly like the "you don't need microservices for everything, you can have well built monoliths too", "not everything must be a single page app", or "not every datacenter should be replaced with a cloud one".

ES specifically has a large list of drawbacks, so not everybody should use it. It would be great if people could tell about how there are many changes of gray between "CRUD-only we forget everything that is not current" and ES, but in a hush to make a point people act like those are the only known possibilities.
