It has been requested quite often.  See the comments around
`pop3-leave-mail-on-server'...

BTW, I don't know why you removed the corresponding warnings from
`pop3-movemail' with this commit:

,----[ git log - gnus/lisp/pop3.el ]

|     Remove pop3-movemail and rename pop3-streaming-movemail to pop3-movemail.

Some mail providers don't offer IMAP (for free).
