Can EventSource be enhanced to support cross-domain requests via

Done.
Great news!
The same-origin check in step 4 under "When the EventSource()
constructor is invoked .." is still present.
According to the CORS specification, a request is not to be terminated
even when the resource sharing check fails. However, when using CORS
with EventSource I think it may be justified since the response is
typically not returned right away.
The Cache-Control request header used with EventSource is not in the
list of simple request headers and a preflight request is not really an
option here in my opinion.
