It does not try to streamline naming standards across various OSes and platforms.
For 64-bit x86 compatible platforms, the names "x86_64", "amd64" and "x64" are in common use. Since the proposal relates to setuptools, I'd suggest to do any such streamlining there, if needed and found necessary. For matching a binary to a system configuration you only to need to make sure that the name used for that particular system is the same. Since os.uname() does not exist on Windows, platform.uname() can be used for this purpose. What we could do is add a new API that returns canonical names for the various platforms. That function could then return "amd64" for AMD 64-bit architecture compatible processors. I'm also thinking about adding a function to do platform matching to platform.py: the function would take two uname() results (or part thereof) and return True/False depending on whether the platforms are binary compatible or not. Some background on the used 64-bit platform names: MS started out with calling the 64-bit x86 compatible processors "AMD64" and used "IA64" for the Itanium processor family. More recently they switched to calling 64-bit versions "x64" and since support for the Itanium processor family is being phased out this will soon become the only name used for the 64-bit version of Windows. Cygwin on Windows uses "x86_64", FreeBSD uses "amd64", Linux uses "x86_64". Mac OS X uses "x86_64" for Intels (and "ppc64" for PowerPCs).
