Likewise, if a file hasn't been changed for 3 months and it is changed today, but I only want to keep 1 month of history, I can NOT simply ditch the 3-months old version.

If that old file is changed today, then what is kept is today's version
(the mirror) and a diff to reconstruct what the file was yesterday. You
can indeed simply ditch any history older than 1 month. In fact, that
"three-months-old" version _did_ get discarded as soon as you made
today's backup. The only thing kept showing that the file was actually
old is the timestamp in the mirror_metadata files.
