Woot Woot!
Speedrunning kind of solves this since the point is to win ASAP, but it feels like there's no good reason to spend bombs before you're "ready" (as in have huge stats and a bunch of bombs and know you can beat the boss) so it would also be neat to have rewards for a partial success like defeating a specific limb or something to make it worth spending bombs even if you can't actually win the fight
