The compatibility options can be kept in /usr/bin/yum without cluttering up
/usr/bin/dnf.

That’s a pure illusion.  The users have a compatibility expectation that *their
software will continue working*.  Compared to asking the users to notice
and work around removal of “obsoleted stuff” in /usr/bin/yum, asking the
users to notice and work around removal of “obsoleted stuff” in
/usr/bin/yum *and in addition to change the command name in their scripts*
is, AFAICT, just making things worse.
