The smoke tests are development-focused, in contrast to regression tests which are focused on maintaining correctness. If time budget wasn't an issue, we would run the smoke tests both with and without feature flags, but we have to choose one. With feature flags makes more sense - e.g., if the developer is working on a feature-flagged feature and runs the smoke tests, it will only test their code if all feature are enabled. 

So, we should make it so all feature flags are enabled when running smoke tests.
