Proposal to drop double slashes from URL syntax

The URI standard[1] says that if an "authority" is present in a URI, it
MUST be preceded by "//".  If an authority is not present, it
MUST NOT be preceded by two forward slashes.  A magnet link does not
have an authority because it is content addressed via a peer to peer
network, and an authority is only used when one central authority (for
instance the IANA for domain names) dictates the allocation and
structure of identifiers within that space.

[1]: RFC3986, in particular:
https://tools.ietf.org/html/rfc3986#appendix-A  (ABNF of a URI)
https://tools.ietf.org/html/rfc3986#section-3.2 (Description of an
                                                 authority)

The W3C deals exclusively with http and its derivative protocols (https,
etc), so we are not held to standards they pass (although we
unfortunately have to deal with the fallout sometimes).

In conversational terms, or even in technical discussion by
implementers, yes they have different meanings than they used to.
However, when you're dealing with standards, you have to use formally
defined words and as such the "classical" meanings of URI/URL/URN are
what is generally used on /this list/ because we^Weveryone else loves to
bikeshed the spec a lot.

Also, the gemini spec specifically says:
> This scheme is syntactically compatible with the generic URI syntax

> syntax. In particular, the authority component is allowed and
> required.
https://gemini.circumlunar.space/docs/specification.html Section 1.2

Now, this is obviously what you're talking about changing, but there's
good reasons to be compliant with the URI spec (which, as previously
mentioned, mandates "//" precedes an authority).  The most compelling
reason being that there's a URI library for every programming language
that's ever been used in the past 30 years, and a main goal of gemini is
to reuse existing specifications where it's not necessary to save people
the trouble of having to roll their own everything.  This is the same
reason that gemini uses DNS and TLS despite their respective problems.
They already exist, they're standardized, and they're well used by
everyone already.


I hope I don't seem rude here, I'm just trying to lay out the general
position clearly.
