Only if 80% of the use cases are extremely simple use cases, with no need for multiple indexes per table, complex queries, common table expressions, user defined datatypes, window functions, asynchronous queries, or a strict stance on undefined behaviors, etc.

The problem I see is that simple use cases gradually become slightly-less-simple use cases. And the pain of switching is 1000x the pain of taking a few extra steps up front and using a better database.

I doubt all the stuff you listed is used even in 1% of cases, except multiple indexes and strict stance. And MySQL supports both.

All the stuff, sure. But I have yet to find a scenario that doesn't involve at least one of them.
