But that's the whole point?   A driver should _not_ (by default) alter the default
behaviour of the other end, IMO, without extremely good reason. There _is_ good
reason for the transaction context manager, but not for the connection context
manager or plain use.

I agree. But the decision is not "this IS to be in the database" (or else no need for
transactions) but rather "this is to be in the database IF other, perhaps not even
database related, things suceed".

Exactly.

Exactly, and thusly easily forgotten, with possibly dire consequences
(in the case of default-commit, as opposed to default-rollback).
