>Runback gives more weight to the boss fight
It really doesn't. You pretend it does, but all it does is waste time. You can let the player create their own "weight" by letting them practice efficiently at hard sections by offering save points and respawn areas at those locations, then letting the player challenge themselves with single-segment runs and whatnot after the fact. Forcing the player to run through the same repetitive non-gameplay trash sections over and over again is just developer narcissism and artificial engagement.
