Why couldn't we implement both methods, in which case we give everyone the
freedom that they require?  It may be easier to have only one option at
compile time with a #define depending on the underlying h/w.  Could you
envisage anyone wanting to use both methods at run-time?  This would,
however, make the underlying kernel code v. tricky and bloated and would
probably not be terribly efficient.

Just my thoughts at the moment...
