This sounds more logical for me and I really like this idea. I think the 
true part is mostly a message instead of a function. However for me as a 
beginner it's more consistent in a expl3 manner. ;-)

So after this small discuss I vote for the following:

\<thing>_case:nn_p
\<thing>_case:nnF
\<thing>_case:nnT
\<thing>_case:nnTF



Best regards
Marco
