I do not found a package called python-unversioned-command
on fedora

https://apps.fedoraproject.org/packages/s/python-unversioned-command
page is empty

and google seems suggest only discussion on the matter

what will be the drow back to use alternative to manage

/usr/bin/python and /usr/bin/python3 ?

we can put priorities for python as  2.7 3.8 3.7 3.6
and for python3 as 3.8 3.7 3.6

and rebuild python3 as empty package that pulls 3.6 (or 3.7 ?) now and 
3.8 in future
