Right, and I wasn't suggesting we remove implies(FilePermission), instead I'm wondering if the compatibility knob and the implNote can be removed. As you know, it dates from the change to FilePermission in JDK 9 to do simple path matching rather than canonicalization.

In any case, I don't want to complicate Roger's cleanup, I'm just noting that it's doing cleanup on a compatibility property that we should have removed a few releases/years ago.
