How much client code would break if pg would start-up in 'autocommit',
and revert to standard SQL after receiving the first 'COMMIT'?
(Supposing - I don't know that - that standard SQL but an implicit BEGIN
at statements issued after a COMMIT).

Benefits: adapting SQL code that excepts standard behaviour would be
easy to fix by just requiring to enter a BEGIN upon opening the
connection.

Just a thought.
