WebDav is not the base HTTP. It’s an extension, and it might as well have been an application running over HTTP.

I agree that support for ftp is waning because the use is waning (although the RFC editor only lets you download the whole RFC repository over either FTP or rsync. Even the index is only available via FTP).

Anyway, my point is not that FTP is that great. It’s that if the claims that pages load twice as fast in HTTP/2 are true, we should not hold off until we see a benefit to every other use of HTTP.
