[3.x] Decide on coding standard for generated code about drupal-code-generator

[andypost]

Great summary 👍
Moreover PHP 8.2 (coming in November) will be supported by 10.0 so makes sense to start discuss its features too

[weitzman]

I support generating code that takes advantage of all those new language features.

I would be cautious with introducing final and private because if they end up in the wrong places then they just make life difficult for site builders. But everything else would be really nice to have.

I think, this can be closed.
I've already updated about half of the generators.
Example: https://github.com/Chi-teck/drupal-code-generator/blob/3.x/tests/functional/Generator/_controller/src/Controller/FooController.php

Hopefully the remaining generators will be updated soon. That's the only blocker for DCG 3.0.

Note that DCG 3.x allows modifying generated assets through event subscribers. So modules will be able to alter the assets as needed. I played a bit with rector, php-cs-fixer and regexp. It worked well for me.
