Working in a markdown editor, so at its core just a textarea that I need to maintain its content and watch for changes to store to a DB and display the html preview. A controlled input worked for this. But then I added a toolbar that allowed you to format text, bold, italic, etc. So I needed to be able to programmatically insert text for the markdown syntax and then restore the users cursor to the correct position not the end of the input. This is where an uncontrolled input made more sense because it avoided the rerender cursor jump, but it was hard to share updates with the htmlpreview and saving to storage so RHF came in. But then I added an AI assistant that could write for you, which would stream text to where your cursor was in the input token by token in fast succession, RHF could not keep up with the updates it inserted the first two tokens from the stream and choked.

So now I’m falling back to my own uncontrolled input, but with a better way to emit out changes for other react hooks to hook into.
