Pelvic tilt is a very small repercussion for something highly, highly unlikely to ever happen.
perhaps i should have been clearer but in my first post i was implying that the hip flexors are not one of the muscles that really gets "trained" when doing lunges, or at least they shouldn't (it is my understanding that they are under much stress if you lunge while leaning forward with your upper body, and that this specific form mistake will cause them to shorten, and to get bigger).
Also, pelvic tilt doesn't occur simply when the hip flexors get large. Otherwise, anyone with a lot of core and lower-body strength would have issues. It occurs when there's an imbalance in the hip/leg muscles (or genetic abnormalities, but that's out-of-scope). If the flexors and extensors are kept fairly balanced, pelvic tilt shouldn't be an issue. Lunges certainly aren't going to cause any problems.
obviously, when the muscles are balanced you should have no stance issues.
however, the hip flexors as far as i know, can get "jammed" if they are shortened and get large enough.
also, i haven't said a thing against lunges, they are a great exercise.
