I'm not convinced this will give any benefit. Currently we just require:

>>> Session = scoped_session(sessionmaker(bind=engine,
...         extension=ZopeTransactionExtension()))

Instead we would require something like:

>>> Session = scoped_session(sessionmaker(bind=engine))
>>> ext = ZopeTransactionExtension()
>>> event.listen(Session, "after_attach", ext.after_attach)
>>> event.listen(Session, "after_begin", ext.after_begin)
>>> event.listen(Session, "after_flush", ext.after_flush)
>>> event.listen(Session, "after_bulk_update", ext.after_bulk_update)
>>> event.listen(Session, "after_bulk_delete", ext.after_bulk_delete)
>>> event.listen(Session, "before_commit", ext.before_commit)

Though this could become:

>>> Session = scoped_session(sessionmaker(bind=engine))
>>> ZopeTransactionExtension(Session)

I'm just not sure that it's worthwhile.
