This could be a workable solution, or you could be asking him to add dozens of lines of boilerplate. Either way, we should contend with the claim of backwards-incompatibility. IMO we need to do one of two things: - Provide a way to restore pre-1.8 behavior of the MySql backend, or - Document a sensible workaround (and I do not consider "add a line before every query" to be sensible).
