It would.  In fact, there would be no work to speak of as IcedTea6
already supports applying it to both hs14 and hs16 (the latter being
much less work).  Having it upstream would simplify the IcedTea build
a little and possibly make it available to more people.

I'm sure Gary (Zero's main author) can also make some other good
points for its inclusion... :-)
