No, it doesn't concern me mostly because I don't keep my funds in exchanges other than the capital that I used for trading and when I'm not trading, I take it out and keep it in a wallet where it's safe. It should be a concern for people who keep all their assets in an exchange platform which is a wrong thing.

Exchanges serve a different purpose, they are not wallets and they aren't supposed to be used as wallets. If one needs a place to store their assets so that they stay safe, they need to use a non-custodial wallet for that purpose instead of using an exchange platform no matter how reputable it is. Use an exchange only for trading and not for storing your coins because anything can happen at any time.
