I don't think this makes sense in general. We can't ship a new copy of a .pxd
file each time a library changes its API. I think it's best to have a library
project maintain the relevant .pxd files, and to distribute them with the
matching version of their releases (or the -dev packages respectively).

The next best solution is to have .pxd maintainers that provide .pxd files as
a separate download apart from the library project itself, and the third best
solution is to push the .pxds into Cython (or it's Wiki) and let them suffer
from bit-rot there.
