Trying to make sense of multi-farm databases

I've noticed a change introduced to the release version in Jun 2016 that
I can't find a bugzilla bug or a detailed comment for, and I wish to
understand a little better: multi-farm DBs, or multi-farm BAT buffer
pools if you will.
* Why do we have them?
* Are BAT "roles", introduced with the patch for this issue, inherently
relevant only with multiple DB farms? If not, why were they introduced
at the same time and with the same changeset?
* Is this considered a "good idea" design-wise, or perhaps an
unfortunate necessity (e.g. due to client needs)?
* When you create a new DB, is there a chance more than a single DB farm
will be created when you haven't specifically requested this happen?
