Yes.

I can kind of see why you wouldn't want this on principle, but could you elaborate? Why should a user have to select which version of python they want for every package, when in the majority of cases the same version will be desired? Having a default doesn't exclude exceptions.
I guess the main problem would be the case where a user switches back and forth constantly between selections, making it a poor basis for variant selection.
If one port selects gcc-mp-4.5, say, doesn't that mean it will be used as the system gcc, and so to compile ports? I can see that's undesirable (inconsistent packages, untested toolchains, etc)
On the other hand, if a user selected +as_python for a bunch of ports as a deliberate (and hopefully comprehended) action because they want to have only one place where they set the python version, I think such problems would be avoided.
