Do you have an example of this? The only things I can think of are where there are debates about having taxonomy strictly follow phylogenetics.
Some relevant threads:

It would probably be best to create a traditional project(s) for these groups. Similar things have been done for galls, leafminers, and other morphologically-similar-but-taxonomically-diverse groups.
