That's roughly what I proposed doing for now, except for throwing out
a release without anyone complaining/requesting it in cases where
there's a major bug (mainly just CVE-worthy ones, I think).

Yes. In hindsight 1.0 was probably slightly premature from a "ready
for distros" perspective, but releasing it as "1.0" was also probably
essential to discovering that. So at this point if the 1.0.x branch is
useful to anyone, I suspect it's users who have musl in embedded
products where they know it meets their needs already and don't want
to risk big changes, rather than distro-type users.

I'd actually be interested in looking at other approaches for next
time we reach a poing of needing a "new stable series" -- something to
avoid unbounded divergence between stable and master. Having a rolling
"well-tested and believed stable except for known bugs X, Y, and Z"
release that's a few versions behind the latest release, and a list of
commits since then which are purely bug-fixes, might be a good
practical option. Such pairs of (base-version,list-of-commits) could
automatically be transformed into tarballs.
