I don't really want to add this plugin to the build. It is inconvenient to have so many exclusions, and I would rather the build system just warn me about mistakes.

We already have a PMD check in our configuration to find unused private methods so I don't think it is adding anything to add this other check. At most it would be interesting to investigate why our rule is not reporting the couple of examples you found in #5738, and improve the rule that way.

many exclusions

Most will be reworked and suppression is normal part of such tools, like in PMD as well, therefor this is not valid argument to me.

investigate why our rule

yes thats clearly why there is a need.

Unused method is only one of many best practises.

This PR is about giving attention and then see, which recipes would help.

recent discovery seems fishy - the king is dead.

then checkstyle-stack using PMD/spotbugs seems only option - long live the king:
