Thank you everyone for responding. Replying to Kenn:
1. This explanation helps me understand more. 2. I realize the drive for the breaking change PR in question is to support Java 17. Would a potential path be to target a more gentle ramp from 8, to 11, and up with a communicated and anticipated date of ceasing support for a particular version?
