The point is there is not a valid use case for that. I could also say that the 
user might want to "rm -rf /", and who are we to tell him otherwise. You are 
already, unconsciously, leaving to kernel 80% of proper power management - for 
this reason, as I already explained a gazillion times and I won't repeat 
myself, the only setting the user might want to be temporarily changed is 
brightness - and we're already striving to provide the best experience with

But again, it does not make sense. You are failing to provide a valid use case 
for these situations, expect "the user might want to do that". But even 
leaving that aside, I might say: what's the difference between creating a new 
activity and configure it and creating a new profile and configure it, if 
that's the sole purpose of the change?
