That's easy: because I didn't think of it.

I can understand what you're getting at with the derived class for dynamic
contexts, such as class members, but how are you envisioning the
call_once_reset function working? Would it take a specific once_flag as a
parameter, and reset it, as if it has never been called? When would this be
used, and how would it help with static destruction?
