I'm playing around with this a bit, and after this CL I have both
third_party\libphonenumber\src with the new code and
third_party\libphonenumber\src\phonenumbers with the old code. Did you test that
moving a collection of repos deps'd in like so works correctly?

When you are done gclient sync with my change, it should say "you are free to
remove third_party/libphonenumber/src/phonenumbers" etc. No?
