Ok, I think the result of this thread and discussion with 0mp is the
following set of actions:

1.) One (1) commit to stable/11 to revert the MFC and bump
FreeBSD_Version again for the removal
2.) One (1) commit to doc to document the new FreeBSD_Version
3.) Fixing ports to use the "new" behavior on 12, both the
yet-to-be-patched ports and the ports that had already been patched
under the assumption that it would still land first in 11.1-stable
4.) Documenting the original commit?

The hard part of point #3 has already been done by 0mp, who has
submitted patches for all of the ports using this behavior. His
patches will just need a bump of the version they're testing to the
12.x FreeBSD_Version and a fix-up on the patches that already landed.

For point #4, this seems like the type of breakage we should be
documenting in release notes or something for the eventual upgrading
of systems to 12.0. All usage of _limits stuff in custom rc scripts
need to be audited, and all rc.conf(5)'s need to be scrubbed for
${name}_limits usage that doesn't make sense with the new context. I'm
not sure what the most appropriate action here is, or what we should
do this far ahead of time for such a thing.

If this sounds like a good path forward, I'll execute #1 and #2 in the
morning (CST, so ~11 hours from this e-mail being sent).
