> The docs actually state quite clearly that developers are discouraged from replacing class components with function components.

Could you link to where it says this? My understanding is that hooks are intended to be the new best practice, and ideally all code would use hooks (which the React team believes are overall better than class components), but the React team doesn't want to force migration pain on everyone. So as I understand it, it's not that a class -> hook refactor is "discouraged", it's more "don't let this be too much of a distraction, and don't feel obligated to rewrite old code".
