I agree that those are valid reasons, note that SSE is available for
32 bit even if most compilers won't enable it by default.

That sounds like the voice of youth. I clearly have experience with 64
bit code, and that experience tells me that it was not ready when I
tested it. Other experience tells me that there is no defining line
between "this technology is not yet ready" and "now it is", so even if
my experience is one year out of date, it is at a maximum at the
trailing end of valid. Yet further experience tells me that you
migrate new users to proven technologies, Linus likes to say "better
old bugs than new bugs".
