I can't see any dependency btw them after skimming through their specification. Worth investigation in its own ticket/PR.

Some background which might be useful, "UseGCOverheadLimit can work independently of UseAdaptiveSizePolicy" from https://bugs.openjdk.org/browse/JDK-8212206

I am leaned towards removing it, as it is effectively dead code.
