What we could do is to use the cpuid-based probing when an algorithm
is needed to selectively load the relevant implementations instead
of all of them.  However, for most algorithms it won't make that
big a difference since all the available ones will be loaded anyway.

Yes cpuid probing does that.

I was under the impression that using cpuid meant that the algorithm
would be loaded regardless of whether it has been requested, as long
as the cpuid matches.

It loads it always correct.
