Is AOL's implementation certified not to have any of the potential
failures that have discussed? I'm not saying that it is impossible to
have such an implementation; but I am saying that it's awfully cocky to
claim it without submitting the details for examination.
For what it's worth, I've worked out how a store can be designed to do it.
In such a store there is no particular benefit to MOVE over COPY; MOVE is
comparable (slightly slower) to COPY in performance. Any store which has
a slow COPY can not have a faster yet safe MOVE.
I daresay that AOL is just a small percentage of overall IMAP usage; and
AOL users using Thunderbird are a smaller percentage. What happens if we
jump off this cliff and discover that there really is no net at the
bottom? What responsibility will AOL take?
