This is still a weird name. "Usage" sounds extremely generic and vague. Maybe
"Handling" instead, even though it, too, is very generic.

How about "UserCookiesExceptionsOverride" ?

[bartfab (slow), 2016/04/12 12:55:16]

I am looking for something that is unambiguous. "UserCookiesExceptionsOverride"
can be read in two ways, either as "user cookies exceptions do override
something" or "here is a user cookies exceptions override." Policy names should
be self-explanatory whenever possible.

I think we can rest this discussion for now though. Let us wait for your design
doc and update CL first.
