Are you sure?

RFC 3986, section 6.2.3 says "In general, a URI that uses the generic
syntax for authority with an empty path should be normalized to a path
of "/"." Note the "in general". The rest of section 6.2.3 explains
that is is scheme-specific.

<gemini://gemini.circumlunar.space/docs/specification.gmi> seems
silent about "gemini:" rules. 1.2 says "The path, query and fragment
components are allowed and have no special meanings beyond those
defined by the generic syntax."

(The Lupa crawler currently normalizes <gemini://example.com> to
<gemini://example.com/> but I wonder if I'm right.)
