You raise a good point, about search engines and the like.  Perhaps I
should specify "interactive clients".

And I get that this kind of prescription is beyond what would usually be
thought of as reasonable scope for a protocol spec.  I also realise that
it's entirely unenforcable.  In some very unlikely distant future where
the spec is being preened for actual IETF consideration I might remove
it.  But for now I want to do my best to make sure that Gemini develops
not just a technical specification but a strong cultural sense of the
right and wrong way to use that spec.
