The kernel has always done a certain amount of "default policy". 

What do you think things like "swappiness" etc are? Or things like 
oevrcommit settings? They're all policies, and there is always a default 
one. So in that sense the kernel always has - and fundamentally _must_ - 
set some kind of policy.

And the default policy should generally be the one that makes sense for 
most people. Quite frankly, if it's an issue where all normal distros 
would basically be expected to set a value, then that value should _be_ 
the default policy, and none of the normal distros should ever need to 

Whether this case is one such, I dunno. Quite frankly, I don't think it's 
even _nearly_ important enough to get this kind of noise.
