[Borgbackup] question about deduplicated size stats

[Chris Downing]

Just jumping in here - not much experience with Borg but I think I
understand the query...

It sounds like what Maurice is after is a way to answer: "If all archives
except this one were not present, what would be the deduplicated size of
this archive?"

If correct, I agree that it would be a useful data point, but have no idea
how complex it would be to generate that information (assuming it doesn't
already exist somewhere).
