It looks like IA64 is going to have an end-of-life on Windows, so that 
certainly has a lower priority.

And I really can't argue much with either of your points, and I don't see a 
compelling reason why we should, other than "wouldn't it be nice if..."

Strongly encourage that this *not* become an initial design requirement.

 1) 64 bit is sufficiently cheap and available now that anyone interested in
    targeting 64 bit should be able to acquire a 64 bit box and OS for nothing
    more than investing in a 32 bit box and OS.

 2) various packages create generated sources, using compiled code.  Which leads
    to two build specifications of the HOST and the TARGET architecture, and
    in some cases dual builds of binaries common to the host and target.

The amount of pain to implement is simply not worth it, unless Windows CE, IA64 
from amd build environments, or other oddball architectures are being similarly 
considered.  But for the first go-around?
