Sure, you could see it that way. That's generally why I also don't use libraries that haven't shown themselves to be durable; I'll use React because it's ten years old and has enough support so that if people do decide to migrate later on (due to technological improvements à la jQuery to pure JS and TS), it's easy to do so, and it's why I don't use much newer libraries like Svelte or SolidJS.

How exactly do things get proven to be durable if people don't use them in the first place?

People can use them, I don't though.
