Is it really necessary to abort the TX? Seems a little antisocial - can't
you just return an error, and let the user/application decide if it needs
to abort?

Do you really mean it when ou say 'Implicitly commit the running
transaction'. I would be deeply opposed to this philosophically, if so. No
TX should ever be commited unless the user requests it.
