We kind of agree on A, B, C. What I meant to say is that because we saw no contribs that will need locks in Drupal 6, we can remove the requirement. I believe I do not want to change API. I will wait with the announcement until temporary tables are gone as well or until it's decided that we are not getting rid of them (which would be a turn of events I am not expecting).
