Why not trying to fit some new framework standards?

I am now working on a big Symfony project, we use Turbo + Stimulus, and honestly, I feel like a kid because it reminds me a lot of good memories.

But ! I really miss some standards of modern JS, like reactivity, HTML attributes, layer of abstraction like selectors, events…

I read the book, I understand the philosophy, but now, we can ? Is it useful to contribute and propose to add these layers, without changing the philosophy ? It’s my main question.
