What's the status of the JIT?

Hi internals I'm wondering about the state of PHP's JIT these days. I understand that Dmitry is still working on his standalone JIT IR framework [1] that's being used by PHP, and that Arnaud is maintaining it from the Foundation/PHP side? In my own benchmarks, done in PHP 8.0 and PHP 8.4; I cannot seem to get any meaningful performance gain from the JIT in web applications or in tools like PHPStan. [2][3][4] The question I'm left with is whether the JIT is worth the hassle? Assuming the JIT's existence impacts the complexity of internal development, I wonder if it wouldn't be better to deprecate it in a future PHP version? To be clear, I'm assuming the JIT impacts internal development — maybe that's wrong? Perhaps I'm missing a real-life use case that benefits significantly from the JIT as well?
