The "supported" workflow is you keep your source of truth in either the monorepo or the external repo. Then you export the current state of the source of truth to keep the mirrors up to date. Then, since we can assume the mirrors are up to date, the inverse transform can be applied to import change requests from the mirrors.
It works well when the assumptions hold, that there isn't large divergence on either side. It can actually be largely automated.
