Well, there might be other reasons to need them. For example, I once got locked out of an account, because I had lost the 2FA credentials (which I did not have in KeePass, incidentally). The webpage let me back in with a recovery question.
Well, technically, it was a recovery code which was just random symbols I had been provided upon account creation, but kind of the same thing in the end.
You replied to the wrong guy, but I think they rather meant it as "unless you're using a password manager (...because password managers are generally capable of storing extra data)". 😅
I mean, even if it can't store extra data in one entry, you could still create multiple entries for a single account and just name the entries similarly.
And to give an example of a password manager intentionally kept so simple that, well, there is a solution, but it is somewhat choose-your-own-adventure: https://www.passwordstore.org/#organization(You can get GUIs for it, which may have a premade solution after all, for example: https://f-droid.org/packages/app.passwordstore.agrahn )
