Avoiding redundant storage using hard links?

[fnurl]

I am currently using offlineimap and only fetch my "All Mail" folder from Gmail and get my labels using the X-keywords header. I was however wondering if it would be possible to do de-duplication of mail by hard linking email identified identical email across folders when e.g. working with Gmail.

Is this something that has been discussed for imapfw?

Not yet because imapfw is still not at this stage of development.
