icc is attached to SO questions about one of two distinct things:
- The proprietary super-optimized Intel C/C++ Compilers, or
- Color-management theory and practice having to do with ICC profiles (named for their parent governing standards organization, the International Color Consortium)
I myself don't know the ICC compiler from Adam but I have plenty to offer w/r/t the ICC color-profile file format. A glance through the question list reveals a litany of posts from enthusiastic specialists, each of whom have one or another form of “ICC” expertise, but never both.
Unlike many ambiguous-tag scenarios, there is really no overlap between the two realms of inquiry in this case. I don't think there's a single value-add to the tag's role representing these two domains; at the very least, when discussing homonyms/synonyms/etc like these, one can typically wring out some forced and unfunny “ICC/ICC” joke, but I've got nothing in this case.
Even though my reputation falls short of the minimum balance one needs to make tag-wiki edits, I can still write up and submit tag-wiki copy changes for review — like many of my peers, I have taken advantage of this. I don't believe there's a way to suggest other actions, like disambiguation. If that is by design, or not, that's fine either way for me; I'm only bringing this up here to illustrate the one issue with icc.
