Request for the inclusion of "FormAlter as Plugin"

What makes form alters special over other alter hooks? why not a plugin for every hook?

We're getting into well trodden territory, such as proposals to improve the hook system generally, or implementing event dispatch/subscribers and weight/priority systems.

A recent example is 🌱 [META] Hooks via attributes on service methods (hux style) Active .

And you have contrib solutions already such as Hook Event Dispatcher → and Hux → with priority/ordering systems. Each have their own way of doing dependency injection.

We're going to need a harder sell on why you want this and what makes your proposal unique.

I think this is covered by OOP hooks https://www.drupal.org/node/3442349 → which is more or less what @dpi said in 2023 but it's landed in core since that comment.
