To add on to Alan's point.  These "extension" names were created simply to represent individual line items in the Profiles.  In many cases these represent a one or two sentence statement in a Profile about an optional behavior or about a specific parameter value.
Any effort to standardize key names and value names across discovery schemes should be kept separate from the acronymic naming in Profiles of specific line items (aka specific key-value pairs).

It's very much the same exercise where the Profile specific options are more narrowly scoped. However, I would imagine the ones created for the Profiles to be a subset of the larger KV space as you named it. If we're going down that road, it would be good to have things consistent. 

What I'm saying (or at least my leaning) is that discovery methods should use K-V pairs as they do today (with standardized K names desired).  Whereas Profiles have a more limited goal of having extension-like names for specific K-V pairs.  The latter names are different animals than the former - not only semantically but also in being short not-so-self-descriptive acronyms (not exactly what you want for K names).

In short, keep these two areas uncoupled from each other and let each struggle down its own path without getting further delayed by each other.
 
 If we're going to not call them extensions, I suggest coining something we can use more accurately then. I don't have any great ideas atm.

As Alan mentioned, him and I threw around names like "profentions" (aka profile extensions), although more out of amusement than practical value.

Practically speaking they should have a reasonably self-descriptive (yet short-ish) name.  Maybe simply "mandate names"?  This also avoids any confusion with extension names and with K and V names that would be used in discovery structures.  This also covers mandate items that are one sentence behavioral descriptions (of either a behavioral allowance or disallowance).
