[My Hero Academia] Will One For All eventually get so powerful that nobody can use it?

As it is now, Deku can use a bit of it, but if he uses too much he breaks his bones and otherwise hurts himself. But One For All grows stronger every time it's passed on, so will it eventually reach a point where so many users have contributed to it that nobody will be able to safely use it?

Maybe.

Deku seems to have gotten supremely unlucky in how the quirk manifested in him, but his quirk changes several times early in his career as he accesses more of its power. Previous holders didn't have this problem, and All Might was quirkless, so the quirk probably isn't too strong for mortal hands (yet). The problem seems to not be the One For All, but how Deku manifested it. His successor probably won't have as many problems as he did.

Still, just to be safe, it would be a good idea to only give it to quirkless people, or make sure the next holder has a durability or defensive quirk.
