Hi, it seems this function has suffered extinction in 5.0 - even before the onslaught of massive global warming?

This would seem to quite significantly limit the flexibility of the make system, as now a multi-directory source has to strictly mirror the module and functor application structure. Worse, it makes it very hard if not impossible to use external (non-basis) sources without physically copying them to my source tree. Well, I guess there is still a way, first run make in the remote directory, dump an image, then re-run in my own directory loading that image - but it is laborious.

Is there a reason why it had to go?
