Creating AP subcats for Actors, Activities and Objects?

I just created a topic Offers unchained for discussions on the Offer activity type and its implementation. Elsewhere there is discussion on supporting Group in various topics.

Would it be an idea to create specific subcats - besides only C2S and S2S - for the most relevant AP Actors, Activities and Objects that need further elaboration, so as to keep the discussion on these more central and easy to find?
