For the open threads. Leaving currently assigned assuming @DanielVeza you wanted to work on this one.

Pushed up a commit that fixes most of the MR feedback. This is the leftover item, need to look into it more.

I think you can use EntityContextDefinition::fromEntityTypeId('entity_view_display') here to simplify

PHPStorm doesn't like it. I wonder if static functions aren't allowed here

Setting back to needs review. Resolved all threads except one, and left a comment about why that one may not work. Unless I'm misunderstanding something

For the 1 thread.

Agreed with the the last feedback item. Pushed up a commit, back to NR

I think we need to document the params as per the annotation class.

As per @larowlan I think we need to add public readonly ?string $deriver = NULL to the constructor params.

Seems to have a check failure

fixed phpstan issue

Feedback appears to be addressed.

Committed and pushed 4fcae3ca53 to 11.x and 31ec7d645e to 10.3.x. Thanks!
