It's questionable that "more releases" == "better". Sometimes software is (ideally) just done (except for security issues). I use a lot of software that has no significant changes since decades. Regarding a libc-replacement I couldn't name a single important thing for the last years.
But of course, no release could also be a bad sign, like beeing abandoned or that is has just no users (testers).
I don't think openbsd libc has ever kept the same version for two consecutive releases (six months). Which doesn't even count bug fixes as a version change. There's always something to add or remove.
you missed the first entry (20180924).
