It'd be considered, but whether it'd be accepted would have to depend
on the size of the performance boost, its portability (how many
platforms/scenarios do you actually get a boost for), and the extent of
bloat/uglification of the code.

I can't personally get excited about something that only helps if your
server is starved for RAM --- who runs servers that aren't fat on RAM
anymore?  But give it a shot if you like.  Perhaps your analysis is
pessimistic.
