Is the melodic minor scale use as the basis of chord progressions in modern jazz? You are generally forced to: Start a phrase at the start of the progression, Build up tension as the chords build up in tension, Resolve tension as the chords resolve in tension, End the phrase at the end of the chord progression, Target any note in the scale (There are no guide tones or avoid notes, though there are, Start and finish a phrase whenever you like (so there’s no limitation on phrase length based on some chord progression), Build and resolve tension whenever you like (because there is no fixed chord progression), Stick to the relevant scale/mode (with occasional chromatic.
