Hi,
I am retiring python-descartes in Rawhide. Upstream died when Bitbucket dropped Mercurial support, and has no intention of reviving it.
Downstream users have stopped using it, and I have removed the unnecessary dependency from Fedora packages, or patched it out after reporting upstream.
It is currently FTBFS with Python 3.10, and thus not installable after the rebuild.
