No plans, but no particular opposition. bottleneck is a good place to
experiment with these optimizations. When they settle, it might be
worth folding them back in.

Doesn't matter.

No. MKL/ACML focus on parallelizing expensive computation like
matrix-matrix multiplication, not things like finding the minimum
elements of an array.
