Would that mitigate the pain, assuming that Steve (or someone else) would be willing to build the additional installers for the transition period? I've done something similar on a smaller scale with the OS X 32-bit installer for 2.7.x but that impact is much less as the audience for that installer is much smaller. Well, the question really is whether precompiled extension modules available from PyPI would work on both compilers. I understand that for OSX, you typically don't have precompiled binaries for the extension modules, so installation compiles the modules from scratch. This is easier, as it can use the ABI of the Python which will be installed to. If you go the "parallel ABIs" route, extension authors have to provide two parallel sets of packages as well. Given 32-bit and 64-bit packages, this will make actually two additional packages - just as if they had to support another Python version.

As far as I know, stuff on OSX is generally built for “X compiler or later” so binary compatibility is kept as long as you’re using an “or later” but I could be wrong about that. Using binary packages on OSX is a much less frequent thing I think though since getting a working compiler toolchain is easier there.
