Having a switch shared by the packages you are developing each one of these being git-pinned in it fits the bill for me.

The only remaining problem is that our build systems are too stupid to track dependencies up to the installed package (in fact, libraries) they use in the builds. This means local repo dev builds don't know they need to recompile when one of the git-pinned (or any other) package reinstalled.

Best,
