I just hate doing version checks when a feature check ought to be
possible.  You never know when it's going to cause trouble.

But yes, certainly being able to handle the backport case would be nice.
When I wrote PEP 402, I was thinking in terms of transitioning the .pth
files to importing a compatibility module.
