It makes sense. One For All=Quirk that passes quirks+Stockpiling quirk.

The previous users simply assumed that meant only strength. Wrong! Turns out One For All passes the previous users will and quirks too. Do I have a problem with that? No. I don’t.
Okay, I get it. Some of you out there don’t like where this is going. Deku’s already powerful enough, right? He’s gonna be this one-man wrecking crew just like Naruto or Ichigo from Bleach, right? While I agree those things happening would suck, I don’t think Horikoshi’s going down that road (at least, I hope he isn’t). Here’s why.
I believe at its core One For All is about raising a person’s physical abilities. Deku’s physical strength will always be at the forefront, with his tactics a close second. The extra quirks will be to Deku what the utility belt is to Batman. The belt helps Batman in his crusade against evil but he’s never overshadowed by it. It allows Batman to do his job better. Does he need it? No. But, he’d be way less effective without it. That’s what I think Deku’s other quirks will do. We even get a hint in this very chapter. Blackwhip came out when Deku wanted to capture Monoma. Sure, if it gets out of control, Blackwhip is monstrous, but that’s not its primary function. It’s basically a lasso. A lasso Deku can use to capture criminals. A tool in his fight against evil. Just like his shoes. Just like his air gloves. Deku’s not overpowered, he’s gaining new ways to do his job.
