This is a contributor-hostile attitude.  The fixes are obvious,
proper, self-contained, tested, working.  You are proposing to hold
them hostage until some completely independent code is changed.  If
you're thinking of a replay of my pmmgr container-subtarget code being
ransomed six months later by my fixes of "pmie -h", no, let's not do
that again.

There is no statement in HACKING that any random incremental
improvement in locality of the code base must - MUST! - be analogously
carried to every other nook & cranny.  If it were a standard, it'd
have been violated at some point by every maintainer.  If applied to
the community as a whole, it would dissuade changes.  If it were a
standard applied selectively to only a few community members, no,
let's not do that either.

Incremental change is a good thing.  Embrace it.

At the time the patch was written, it was not localhost-only.  You did
not respond to later review comments at [1], so we don't know what
your intent is with respect to remote monitoring of pmda status.  IMO
that remains a valuable service.
