That would be awesome! I can't count the number of times I've asked why one would want to use cpanm, and the only answer I've gotten (that didn't lie about cpan) was that it works better on systems with less space (such as embedded systems), and that it hides the output of the installation tools when there's no error (which still hides useful information). (Obviously, cpanm is less configurable, but noone actually needs the extra configurability of cpan, so I won't count it against cpanm).
