Couldn't we only allow digest-based 401/407 authentication for 
subresource loads so an attacker cannot simply obtain unencrypted 

The latest WebSocket protocol spec [1] says:

"This protocol doesn't prescribe any particular way that servers can 
authenticate clients during the WebSocket handshake.  The WebSocket 
server can use any client authentication mechanism available to a 
generic HTTP server, such as Cookies, HTTP Authentication, TLS 

Without HTTP Auth and the difficulty/performance issues of doing TLS 
auth in pure JavaScript it seems we are left with a cookie-only 
authentication option.

Disabling support for Basic HTTP Authentication but still ticking the 
box for HTTP auth, with the added benefit that all such HTTP auth will 
be encrypted, seems like a win-win here.
