Yeah. I'd consider renaming the option ":domain" or something.

So, here's a thing: Faraday only takes the scheme and domain parts of the URL into consideration with `Faraday.new`; it ignores the path part – The leading `/v0` has to be passed in as part of the request.

If desired I can parse the version out and hand that to the url builder, but it's a bit more involved.
