I can see why you want to do this, but I'm not sure it's a good idea.

One reason being, *IF* we were to ever end up in the situation where 
only source packages were uploaded, and some build service constructed 
the binary packages, that builder would not be permitted to download 
arbitrary files.

Yes, this is not permitted (at the moment).  All versions of a package 
in the package set for a given arch must lie on the same path.

(This limitation is tangled up with how we determine if a package upload 
is permitted, so isn't straightforward to remove)

Move the existing 2.19.37-1 x86/x86_64 package to noarch, then upload of 
2.19.42-1 will be permitted (using cygport 0.22.0 or later, which knows 
to upload noarch packages to noarch/ paths)
