It that it seems to be the occasion of a lot of disagreement with the
document.  That is, in many cases, perhaps the advice should simply
be, "The ZSK/KSK split is useful in some circumstances, but for most
applications one key is sufficient."  Or some such.  I'm not proposing
this text, I'm asking.

Sure, but this may well be the exception and not the rule.

Nobody can ever know that for a fact, because it would require proving
impossible that such a key could be cracked.  Predictions of future
impossibility are hard to prove.  This is a question of trade-off, not
facts, and one of the questions is the degree to which two keys
themselves introduce risks that aren't offset by the gains they might
produce.  I simply don't know the answer, but it seems to me that EKR
is asking the right question.
