But all this stuff we are discussing is for the user, not for the
distributor.  A user always knows which version(s) she uses, so she
can set the minimum versions accordingly.

And if worse comes to worst, one can always be conservative.  It's not
a disaster not to invoke a command that was back-ported.

I find the alternatives more complex and not much more useful.
