I hit "Send" to early, apologies, here is the rest of my email:

Could you please share the package spec file with us (Python Maint team at Red
Hat, specifically Tomas Orsava and me) before you actually push it to EPEL, so
we get a chance to review it (and maybe test it)?

On RHEL 8, if there is something that provides /usr/bin/python I can't find it, nor can dnf.

I've been running RHEL 8 since 8.0, I'm currently at 8.4 and this is what I have.

# dnf provides '/usr/bin/python'
  Error: No Matches found

# ls /usr/bin/python
  ls: cannot access '/usr/bin/python': No such file or directory

# which python
  /usr/bin/which: no python in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin)

On Fedora, it's rather simple, just look at the contents of python-unversioned-command

Two files, no scripts or triggers.

# rpm -ql python-unversioned-command
  /usr/bin/python
  /usr/share/man/man1/python.1.gz

# ls -lh /usr/bin/python
  lrwxrwxrwx. 1 root root 9 May 18 03:48 /usr/bin/python -> ./python3

# ls -lh /usr/share/man/man1/python.1.gz
  lrwxrwxrwx. 1 root root 14 May 18 03:48 /usr/share/man/man1/python.1.gz -> ./python3.1.gz

It looks like it will be very simple spec file.

I'll probably just cut it out of the Fedora python spec file.
