I don't disagree with this change being a problem, but...

"FTP's transfer efficiencies over HTTP"?  A TCP socket is a TCP socket.
An HTTP transfer of a file (not including things like logins and such)
requires less communication than FTP.  HTTP opens a socket, sends a few
dozen bytes of request, and gets the file.  FTP opens a socket, has to
log in (even for "anonymous" FTP), has to request the file, open a
second socket for the data transfer, and then gets the file.

I don't speak for anybody but myself - that's enough trouble.
