Maybe Tramp does not support http and https URLs initially.

Okay.  It seems that ftp://user@host//foo is an illegal URL, so I can
assign any meaning to it that I like.  Hence, I'll define it to mean
the same thing as ftp://user@host/%2Ffoo.

Do you object?

Yes.

Though I am afraid that there might be a standard which defines some
completely useless meaning to these URLs from Tramp's point of view.
For example, if there is ever a standard that says that
ssh://user@host/ should open a terminal window, then Tramp can't
meaningfully support it.  (Tramp will show a dired buffer of the home
dir of that user on that host instead.)

The ftp standard is not supported by whom?

Tramp does not currently use URL-like syntax, but it does support ftp
(on Emacs, via Ange-FTP).
