I disagree. The ability to mount HTTP file systems is actually built into
Windows. I don't think FTP is supported.

FTP is a very peculiar protocol, I have implemented it several times and it
was awful to do even before NATs got in the way. It is not really a
separate protocol, it is an extension of Telnet.

Oh and having to redo every transfer because the default mandated by the
spec was to damage the file assuming a charset conversion was ridiculous
even for the time.

We are inventing the future here, not keeping the past alive. As usual, I
have been spending most of the two weeks between the drafts cutoff and the
IETF meeting working on my documentation tooling. Why is it that 91 people
using FTP out of over half a million is considered a serious issue? Could
we have similar concern for the people who would like to use professional
tools like Visio, Word, Powerpoint, Adobe etc to create diagrams? Right
now, there is only one tool that I know of that supports the obsolete,
deprecated, WAP-SVG required.
