If acceptable I don't mind also updating this list. Alternatively we can upstream our RefasterRuleModifiers check, which normalizes modifier usage by Refaster rule definitions more generally.

Thanks, updating the list until we get around to deduping them SGTM

That also sounds good if you have time/interest, but it also doesn't need to block this PR

Top; will do.

I'll make a note to consider this later then ✔️. (When we contributed #3813 and #2232 that caused some issues for downstream users due to a name collision (PicnicSupermarket/error-prone-support#622 and PicnicSupermarket/error-prone-support#686), so maybe this time I'll try to find an alternative name; hehe.)

Of this list, currently there's only a test for javax.inject.Inject, so I didn't add any test cases for these new annotations, either. Let me know if I should. (I did test these changes against a collection of real Refaster templates.)
