Also it would be great to migrate components and directives to standalone versions to be able to use Directive Composition API and etc.

What are the plans about standalone components?
Will be a big refactoring needed with XxxModule, e.g. MessagesModule?
Or will e.g. MessagesModule have the same name, but be converted to a standalone component under the hood instead?

@j-s-fesfwd Given how opinionated Angular is, I would be very surprised to see them using the XxxModule naming convention if it is not truly a module.

Since standalone components are interop-able with normal ones, I'd speculate they will unblock people from being able to use v15 first before worrying about making them standalone which would come in a release at a later date.

They could either introduce a breaking change and force every component to standalone, or they could include both module and standalone options (which seems like a pain to tree-shake and would probably require import changes).

I guess we will see what the community does. If it becomes customary in the library community to provide both options, I reckon they will follow suit.

However, I'm just speculating and would love to hear from a PrimeNG dev. Angular 15 is the hot topic right now, I'm sure they've got it covered. With such an integral library like PrimeNG is I'd imagine they will get an update out relatively quickly.
