As said above OfflineIMAP will create a blend copy of your emails and you will loose quite a lot of very interesting features when copying them to a standard IMAP server. That said I understand the need and will think on an approach to allow users to leave Gmail for another IMAP server in v2.0 Another point is that Gmvault is meant to be easy to use. OfflineIMAP is a very good tool but it is meant for advanced users like us as Gmvault is meant for users with very little computer knowledge. Gmvault v2.0 will go further as it will have a GUI (while still having a CLI mode) to allow my Granma to backup her emails :-).
