AOT requires a lot of fiddling around, and might break the application unexpectedly, with very weird errors. It is mostly targeted to Blazor (WASM) and for serverless functions.

The default runtime and JIT are fine for most use cases.

It hasn't been my experience. Native AOT does come with some limitations [1][2], but nothing awful. Mostly it's that you can't generate code at runtime and you have to tame the code trimmer. Just don't ignore code analysis warnings and you should be good.

Making your CLIs start fast is also a huge use case.

C# AOT may sometimes require fiddling around, but in my experience a lot less fiddling around than what my alternative used to be, which was to use C++.
