I might be completely off my mark here, but no, I don't think it does.
If it did, Overbite extensions would've implemented gopher directly in
JavaScript instead of redirecting to web gateways.

Let's forget Javascript for a moment and pretend this is some new
client that has this capability. How would it know which data to send?
And which format to use? I guess it could _tell_ the server in
the ?possible=params format.

Thanks, that made it very clear.

I'm using Gophernicus already, no need to plug it ;)
