Fedora's Python version migration needs to be coordinated with
RHEL.
The most important step would be to *NOT* change /usr/bin/python to /usr/bin/python3, but
have it provided by a separate (non-default) package. For Fedora and RHEL, this would mean
the separate package does not get installed and all scripts still requiring
/usr/bin/python will fail. Sysadmins then have to choose whether to install the compat
package or port their scripts.
