@scottmarlow, for EE12, we're removing the tags TCK from the platform-tck, right? Should this instead be a PR against: https://github.com/jakartaee/tags? Do we need a PR to remove the tags tck from the platform-tck for EE12? I know there was some discussion here: jakartaee/tags#270

Oh right, thanks for the reminder! We already moved Tags tests over to https://github.com/jakartaee/tags/tree/main/tck/src/main/java/com/sun/ts/tests/jstl so 👍

Yes!

Yes

I know there was some discussion here: jakartaee/tags#270

👍

Merging even though the Tags TCK source has been moved to the Tags spec repo.

FYI I created the upstream PR jakartaee/tags#287.
