That's not a micro optimization, it's a massive performance hit if you
force those 32bit archs to do 64/32 all over the place.

Linus could just say he doesn't care about 32bit and everybody sane
should just get a 64bit machine.. but I suspect that's a few more years.

Although I hope not too long, even my phone could do with more than 2G
of memory.

Perhaps it wouldnt; if people didn't keep adding junk to the system ;)
