It makes it trivially simple to have different media retention times for
different types of jobs in order to keep the quantity of backup media
under control.

Personally, I have a Full pool on tape, run monthly with twelve months
retention; a Differential pool on disk, run weekly with three months'
retention; and an Incremental pool  ondisk, run daily with one month
retention; and it's easy to automatically expire and delete opr recycle
(as appropriate) each volume as it gets past its sell-by date.
