Any plans for SaveToFile, LoadFromFile in TIDMessage?

Any plans to provide persistence for an IDMessage?  We heavily rely on
archiving and manipulating email messages after they've been accessed from
the server.  I know I can descend from TIDMessage with my own functionality
to do this (with the JPSoft example), but I'd sure like to see it built in
to TIDMessage, so I don't need to worry about tweaking my code with every
Indy release.
Thanks.
