I'd suggest you just start doing that, perhaps with an email to HN mods requesting support for Gemini URIs.

I'm pretty sure that you'll get shot down (politely) the first few times, but the requests (and appearance of Gemini URIs) will give an indication of whether or not the protocol itself is gaining in usage.

I do have a Gemini browser installed on a few systems, but use it rarely for want of content or presentation of links. OTOH, I've watched the rise in prevalence of Mastodon / Fediverse links on HN with interest.
