Is the current rearguard format expected to live "forever"?
No, the idea is only that it's rearguard "enough". That is, even the rearguard is on the march, and every announcement of the publication of the rearguard-format tarballs has said that they're intended to be temporary. The next release (2019b, which should be reasonably soon) may be a good time to skip my publication of a rearguard-format tarball. The main use of the rearguard format seems to be last-minute updates for people using TZUpdater and the like, and we'll almost surely have a release 2019c before October anyway so people can update then. People who need rearguard format tarballs before then can make them by running "make rearguard_tarballs".
