MarsSeed [1] filed a deletion request for python-healpy-git [2]: Broken, unmaintained Python2/Python3 VCS package from 2018.
Upstream only supports Python3. PKGBUILD does not declare provides or conflicts, so nothing depends on the subpackages. AUR has a properly maintained stable package for the latest release. [a] Not useful to keep this defunct one as is.
