selector: 'ImportDeclaration[source.value=/^react-dom(\\u002F(server|client))?$/] ImportDefaultSpecifier' – this could work with only one additional entry using a regex but its clearer to separate out all the error messages

I'd replace lines like this one with a namespace import as well to be consistent.

Ah I missed these kinds of imports, let me see if eslint can find them too

This case is interesting. I think that the initial problem was that:
import ReactDOMServer from 'react-dom/server';is wrong because React plans to no longer export default facebook/react#18102.
This change goes after something else but why not.
