My argument is that using a metadata-preserving archive format allows  
a programmer to control that stuff and also allows setuptools (or  
distutils, I guess) to ignore that stuff.  Inventing a way to pass  
that information through the metadata requires the programmer to  
learn and use an extra configuration on top of what they already do,  
and requires setuptools (distutils) to pay attention to that stuff.

You mean a bdist?  You can't "cross-compile" and build a bdist for  
Linux on Windows (can you?), or vice versa.  I think we're only  
talking about "non-cross-compiled" bdists here.

A metadata-preserving archive format wouldn't make this harder, and  
it might make it easier.
