Thanks!

Instead, enough of the prefix to uniquely specify the action is all that is required (e.g. "port depe ..." instead of "port dependents ...", or "port va ..." instead of "port variants ..."). If the action isn't unique, port lists all the actions it could be and doesn't process the action.

Note that "port list" doesn't do what you may think it does. See the FAQ for details:

http://trac.macports.org/wiki/FAQ#portlist

I agree with Joshua that we shouldn't add more verbs to MacPorts that duplicate existing functionality. In this case, things like "port echo active" or "port installed inactive" already work.

This is definitely useful; I have a shell script I've been using that does this and it would be great to have it built-in.

This would be great; more convenient than running "du -sh /opt/local/var/macports/software/PORT/VERSION"

Sounds similar to a shell alias I have set up "port ll" which runs "ls -l" on each item of "port contents". Much of the output from "ls -l" I don't really want, but seeing the size is nice, as is seeing where symlinks point to.
