Oh sorry, I don't mean replacing the documents entirely. what I've seen is loom videos replacing sections of those documents (where in the past you would have expected screenshots + text to explain decisions or a design). To me, there may/may not be more total information, but the information density is much lower. I think my hierarchy as a reader is: document with good screenshots and text > doc with good loom video > doc with bad loom video > doc with no screenshots / bad text.
