Posts feel less valuable as files as they are of the moment. I don't need this comment as a docx, thank you all the same.

So I agree.

Maybe building it that way opens possibilities I can't see?

But for functional apps it seems useful to have a file you can download and use somewhere else. Images and movies are a great example. I can record a video in Loom and chuck it on Youtube. Youtube can't lock me on that video. it is my file. Imagine if that was not the case. It would suck.
