We are 11 days into the 6 month development/stabilization phase for Symfony 7.3.

On the flip side, that means you can help out by reporting features of the component that are not developer friendly, and telling us what things we must not forget to document! 😉

Actually, the reason libraries use the annotation is because this is near impossible to guarantee backwards compatibility on between versions. If you accept this risk - as mentioned in the first post - you can use them.

I would personally just suppress the check in the static analysis config.

I don't think the source is publicly available

This is built by the Laravel Herd team (and comes with the laravel CLI installed).

From what I've heard, it's doing the same as the frankenphp binary (frankenphp.dev/docs/#standa...). It's a statically compiled version of php-src + some common extensions and available as a single file binary

If you encounter anything concrete that you find especially messy, feel free to open a issue at github.com/symfony/symf... or ping me anywhere you find me.
Always good to hear user feedback! :)
