A very basic reason: SHOULD is only for things that are strongly desired by
all implementations. If we have a strong algorithm for a MUST and another
strong algorithm for a SHOULD, I see no point to tossing another SHOULD in.
Many developers try to implement all SHOULD-level specs, and this would
cause needless software bloat with little definable benefit.
So IDEA as SHOULD would guarantee backward compatibility? Fine. I'd prefer
MUST, but I see the problem.
And, again, I would strongly lobby against any MAY list. A list of IDs for
all known algorithms identifiers is enough.
That's a MAY list.
