Yes, I've written a few scripts to do bulk operations in IMAP and it definitely seems like a protocol that just grew and the was documented but that is no excuse for clients doing:

Fetch message 1 header.
Thank you.
Fetch message 2 header.
Thank you.

when they should be doing:

Give me all the message headers.
Thank you.

The same goes for moving/copying messages. IMAP support always seems to be bolted on afterwards

IMAP support always seems to be bolted on afterwards

Sadly, that's true. I can imagine the development going something like this:

"Aaaah! There are all these weird mail stores out there. Let's abstract out a generic mailstore and specialize it for each actual store."

"OK, what can a mail store do? Well, let's look at POP3 and see.."

The generic mail store API is then designed around POP3 and has no idea how to use the more advanced facilities offered by IMAP. :-(
