clean, distclean, mostlyclean, and maintainer-clean are from the GNU
Coding Standards (GCS).  Many projects have extraclean.  So this is
tradition of sorts.

AFAIK, the issue at hand is not the speed, the issue is to know what
generated files get deleted.  Some builds require a specific target
from this list to be run before the build.  For example, if you weant
to reconfigure from scratch, you want distclean.

Because the GCS says otherwise?
