There are very few, if any Gopher+ servers. And because of that, there are very few clients that support it. And I do see some clients attempting TLS connections to my gopher server, and it clutters the logs with garbage attempts.
I think it is a bit of a chicken and an egg problem. There are a few Gopher+ servers out there (pygopherd gas Gopher+ support for example, which is reasonably widely used), and the Gopher+ protocol is pretty flexible and designed with the metaverse in mind originally (see GopherVR from the original authors).
It is a shame that a lot of current Gopher users seem to be strongly against anything apart from standard Gopher, when the original authors of the protocol had much grander ideas for interactivity & visual interfaces. Sigh.
https://github.com/gopher-protocol/gopher-plus/blob/main/gop... specifically mentions 3D representations of Gopherspace. They also provide provision for a "general purpose" scripting language - I think Javascript would fit the bill - there and in section 2.8
A little off topic, but which gopher server (and any management tools? ) do you use for hosting? I'm in the process of setting up one and trying different ones out but haven't settled on one yet.
I wrote my own gopher server [1] that works for me. I haven't looked at any other gopher servers in any detail to give a recommendation (unless you want to use the one I wrote).
