The problem would be that there is no way to start
rewriting a tape, and then "stop" before you overwrite the important data at the
end without destroying that, too.
The only way out of that would be to come up with a "tape
reclaim" feature where you read the important data off the volume, appending to
another tape. THEN recycle the entire first volume. This is what Tivoli TSM does
to valid data on a tape of mostly expired data.
Mixing retentions in a volume like that should be
avoided.

No, it will not. Bacula will not reuse that space until it decides to
recycle that volume.
