Even though I do agree that the total recording of sessions is not nice, such tools can be extremely important during early stage testing with your web app's UX. Especially for solo founders who don't have colleagues to tell them that they can't figure out how to use your app :)

Nice way would be to do some recording for a week or so. Get any sessions that obviously were quite long and the user didn't achieve anything. Go through them and try improving UX so the user won't get stuck there the next time.
