Windows 8 is the first to require SSE2 . I'm sure it's no coincidence that this became the default in VS 2012.
There is probably a small minority of users that upgraded to 32-bit Windows 7 on old hardware. Python 3.5 excludes them, but I don't think the build should switch to using /arch:IA32 just to support them. If a user on such a system really needs 3.5, it's possible to create a private build without SSE2. Most packages that have extension modules will also have to be built from source instead of using prebuilt wheels.
