The reasoning is that if the zone is dynamic and named can see your private
key, then that's a hint that you would like named to keep your signatures
from expiring.  (Because after all, why wouldn't you?)

But, even if the zone is dynamic, if named can't see the private key, then
it should leave your RRSIGs alone.  If that's not how it's behaving, that's
a bug, and we'll address it very soon.

I agree that option would be a good thing to have.
