It's acceptable to have tearing with swap interval 0, and tearing is surely preferable to having out of order frames. All else being equal, we should prefer the solution that leads to the best visual experience, which could be either doing our best to minimizing tearing, with the risk of being inconsistent about it, or providing consistent tearing.
