Theoretically true, but there are indeed some zones, such as some CDN
zones, which for which the number of possible RRsets is so great that
in practical terms you can't precompute and store them all.

You can argue against the legitimacy of that architecture, but that's
a different claim.

That said, I basically agree with you that a perceived need for
on-the-fly signing is not a real blocker for most of the non-adoption.
