well, I never claimed to be surprised. I was only triggered by the 
reference to our _docs_ as we've put quite some work improving on that.

but honestly, lets not further drum that line;) it leads nowhere. I am 
with you: there is room for improvements. if you have a PR, please think 
about contributing! we'll be working with you / merging ..

I am aware, but no, it's designed like this, because WebSocket requires 
a HTTP URL (with potentially path components, query parameters etc) in 
the opening handshake while the _transport_ does not necessarily have that.

Autobahn allows you to run WebSocket over basically everything that is a 
bidirectional byte pipe: TCP of course, but also Unix domain socket, 
pipes, Tor onion services (via https://github.com/meejah/txtorcon) and 
even serial ports!
