Maybe Microsoft could help out by removing the 7-10GB of x86 and x64 binaries in SysWOW64 and System32 that serve absolutely no purpose whatsoever on an RT device except to take up space.

Are you sure they do that? I'm pretty sure they don't have a SysWow64 directory and all of the dlls in System32 are ARM binaries on the RT.
