The problem does exist, as Micheal has explained in so many words.
Please trust him, as I do, that he knows what he is talking about, and
would have solved this himself if an easier solution were possible.

I see no significant complexity in adding a version test.  We do that
in umpteen other places with many other programs.

Again, please trust Michael on that one.  We will not make any
progress if we start second-guessing every request and decision of our
peers, especially after you already suggested the upgrade, and Michael
already explained why he thought it wasn't the best alternative.

Please.
