Why? Is your goal to make it easy for some entity not the authority
for a zone to forge data in that zone?

Total nonsense. The on or off line signing question is pretty minor
and completely orthogonal to the channel versus origin authentication
question. As soon as you have a zone with dynamic update, your are
shoved in the direction of on-line signing, it doesn't take mixed case
non-ascii.
