OT: Enhanced IMAP protocol

[ram]

Would it be practical to have common protocols like IMAP to support
enhanced features

For eg. 

IMAP protocol may possibly support change password. 
A IMAP server administrator may optionally configure a change-password
hook  on the server which would change the password on whatever backend
he uses for eg ldap or a RDBMS or  Active directory
 
The advantage is that the MUA can support change password and the user
experience will be a lot better having only a single familiar app to
deal with. 

That will be a lot easier for admins to tell the users to change
password regularly rather than giving them a new link and asking them to
change password ( .. and that mail looks more like a phishing mail )
