The Microsoft DNS Server overwrites the on-disk hints file with the
results of a successful priming query (or, at least, it used to the
last version I checked). As long as you take some obvious
precautions, this sounds like a great idea to me. (I like your idea
of requiring the same response multiple times before committing it to
disk.) The server could also clearly rename the previous file as a
backup (and perhaps even keep two or three previous files), just so
the change wasn't completely irreversible.
Here's my vote to put this feature in BIND!
