And then you have to keep merging master into your embedded branch
every few hours to keep up. It's a waste of time. Instead, you should
just put a modified foobar-1.2 in your own repository and rely upon the
package manager's extensive and clean handling of multiple repositories
to avoid having to do any merging yourself.

There are uses for merges, but working around the shortcomings in a
package manager shouldn't be one of them. Migrating to Git should be
about addressing problems with CVS, not about addressing problems with
Portage.
