Please file a feature request bug for gentoolkit/eclean.

If I can ever get caught up with other things or we get a gsoc student
that needs some extra work...

Also with eclean and emaint rewritten (by me) so that eclean could use
emaint modules directly.  I have thought a few times we might migrate
eclean from gentoolkit to emaint module(s)  They can even be installed
separately from portage via ebuild.  The emaint system is fully modular
with a plug-in system.
