Summary

Motivation

that I made it so that it's not possible to make a custom component vertically resizable...

An easy first step would be to replace this component whitelist with an opt-in prop, as you said - actually this list of components inside a component wasn't a great solution...
Besides that we can definitely discuss this whole topic more deeply - I was working on improving vertical resizing but it still had some difficult bugs/issues and so it needs some more time/work dedicated to it.
