Building each directory (in meta mode) is all that is/should be needed.

Yes the results are stable - in the absense of bugs in makefiles.
I think I fixed all those in the projects/bmake branch, but it is easy
to introduce new issues.
Anytime a makefile changes its behavior based on the existance of
something it risks churning the dependencies b/w clean/update build.

This same tech has been used by 1000+ engineers daily for a number of years
now, it has made it much harder for them to break the build.

When we've added targets to build system packages etc, then that should
be simple.
I still need to catch up with what bapt has been doing on that front
though.
