zope.browser is supposed to be a zero-dependency spot for commonly-used
interfaces:
This package provides shared zope browser components without other
dependencies.
So I wouldn't move anything depending on zope.location into that
package. Your new package idea sounds better.

Frankly, any code using a testing stub which is that heavyweight needs
to be refactored.
