It’s too hard to change anything if one believes in laws, rules and the general idea of a fair justice. They don’t have this limitation.

One of the problems that annoyed me in the past is the complexity and ambiguity of deleting an email over IMAP. Depending on whether it’s the last label of the deleted email, deleting an email from a label’s directory either removes a label from this email, or actually deletes the email.

Considering labels are very non-standard, which caused trouble over IMAP since forever, I wouldn’t count on that part.
