I don't think this is a strong argument against this feature. The 
implementation of this feature will be pretty straightfoward - only a 
small part of the code has to actually change its behavior and it can do 
without changing the interfaces it already relies on. On top of that, I 
don't think it can be done "nicely" in userspace anyway.
