I see and agree.

Which will be in a month or so. Also works with current CVS versions.

Of course.

Since this is a step-by-step enhancement and has no negative
effects on the behaviour I see no reason why it shouldn't be integrated
into CVS step-by-step.

Of course it will be tested though it will only get wider audience
when it usable in CVS before the release.

The MMX builtins should partly work with 3.0 up already but of course
you're right that there's little point in changing working code in
favour of experimental one. However I certainly wouldn't want to start
hacking altivec ASM again after all the builtin development now. :)
