I think the confusion around this stems from the phrasing in the Gemini
spec where on one hand it says that the scheme may be omitted but on
the other hand that in that case "gemini://" is implied, which in its
whole is more than just the scheme.

Strictly speaking, ":" is not part of the scheme, (and "//" is not part
of the authority), so what we'd really end up with when omitting the
scheme from the absolute URI is "://gemini.circumlunar.space".

"//gemini.circumlunar.space" is only defined in RFC 3986 as a "relative
reference" as opposed to an "absolute URI".

The Gemini spec could really use some clarification here, guided by a
careful reading of RFC 3986 in order to get the terminology right and
define the allowed syntax in those terms.
