I don’t see any problems in Webstorm and got the idea from a Visual Studio forum or so. You still need to import the named imports from React though, such as useState, useEffect…
It’s very annoying to import each file individually, and there was an early bug where doing so caused the page to load very slowly during project growing.
It’s fine. They can remove it anytime, but it’s a great safeguard because it prevents a very common mistake: working in React and forgetting to include the import at the top. And I don’t think it compromises any other aspect.
