At O.S. Systems we used some variants here.

We started with forking and moved to combo-layer script. The
combo-layer works for most case but it fails badly with empty merge
commits and like. So it works quite fine for Yocto use case but not as
fine for company workflow.

In the end we choose 'repo' and we provide some 'platform' for
customers where we link all need projects in a single .xml file; this
scales fine and is quite easy to use.
