I vaguely remember that pipenv retirement was briefly discussed here on
the ML, yet I was surprised that F40 doesn't have pipenv anymore.
IMO, this would have been announced more prominently as a self contained
change, as I expect more python developers to find out this too late.
Also, the official guide on
https://developer.fedoraproject.org/tech/languages/python/pipenv.html
should have been updated as well.
