those are ladspa plugins... some of which come from overlays... we won't be pulling ladspa plugins as deps of anything using ladspa: audacity gets ladspa support and its up to the user to install the plugin he wants
So USE flags exist to allow users to choose if he wants to install them or not. If there is a USE, he wont have to hunt around for the plugins.
use flags are there to enable/disable functionalities of packages installing or not a ladspa plugin does not change anything in the audacity package, moreover, if you change an useflag to install a plugin it will rebuild audacity needlessly...
I think there are a few package which do employ this method. As of the current time, this is an enhancement - http://bugs.gentoo.org/show_bug.cgi?id=327701 Maybe you should just produce elogs of the list (in an emerge friendly format).
