Why? I thought this was some transient error, and that we prevent a bad revision from enterting the repository. > Should we add a way to turn off the new validation? If you're saying that this can prevent people from committing new revisions, because a wrong pred count in a transaction is a permanent, rather than transient error condition, I think we should pull this revision from 1.7.x. But why do you think that every transaction will have a wrong pred count once one transaction had a wrong pred count?
