If Jose Alberto wants to run the depend task (i.e. not disable it),
the whole dependency checking will run once for each compilation unit
instead of once for the complete build.  And this is sloooow.

Don't think so.

IMHO the opposite is true.  You don't want to run depend unless you
know you've changed the non-private interface of a class or
interface.  No need to recompile all classes depending of A if I only
change the implementation of a method in A.
