I agree, that is certainly more important :)
I'm mainly just curious to know about how the main contributors feel
about
these things, and whether these things will be implemented/planned, or if
they violate some fundamental language principles...
Basically, I really want to start some major work in D, but before

Well, __restrict was mainly added to C (IIRC), to allow loop
vectorization. In D, we have explicit array operations, which carry a
lot of the same caveats as __restrict, except are checkable.
It's for far more than vectorization. Any place that has redundant loads
can benefit from __restrict.
I recommend this presentation on the subject:
http://www.slideshare.net/guest3eed30/memory-optimization
It's about memory optimizations. Aliasing issues start at slide 35.
