… *now*, but *will be inconvenienced later* after those “a few more
releases” when you are planning for the yum command to go away.  The total
breakage and total impact on users is the same, you are only arguing for a
different timing that makes it seem like a smaller breakage.

(And separately, I don’t buy the argument that this
redirection-with-a-message is how users learn about the new tools.  This
way they only learn about the *most useless* part of the change, namely
“that old thing the system used to do?  It can do the same thing, but in
addition you have to learn a new command to keep it working“.  It doesn’t
teach *the useful part*, “here are the new features and here’s how to use
them" at all.)
