Hi Folks,

thanks for your inputs on whether/how a site can determine whether it
is playing a 1st or 3rd party role wrt a given request.

I think the important likely consensus that I see is
 a) Sites are likely to behave different in 1st and 3rd party contexts
 b) There are multiple feasible ways that allow a site to determine
    whether they are 1st or 3rd party
 c) We do not want to prescribe 'the single way' to do this
 d) We should give examples how it can be done

Do you agree in general?
