Of course I care. All I try to do is to prevent going from one extreme
(all focus on P4s) to the other (ignore P4s completely).

Even ignoring this one case here, I think it's in any case useful for
userlevel to tell the kernel that an anonymous memory region is needed
for a stack. This might allow better optimizations and/or security
implementations.
