dovecot - Mar 2006 - POP3 extension to accept UIDL ranges?

Greetings,

is anybody aware of an extension to POP3 that supports UIDL ranges?

It would be very useful for keep-messages-on-server setups (yes, I know,
IMAP4 domain) to be able to do UIDL 21-42 to obtain just these 22 UIDs
(this would always have to be a multi-line reply, just like UIDL without
argument).

If such a thing does not exist yet, perhaps a keyword such as
"[X]UIDLRANGES" in the CAPA response might advertise this feature to
clients.

Regards,

So, if no POP3 clients support this, why add an extension instead of  
using IMAP?
