Is there a real requirement here for this to be a dynamic listing as opposed to something that can be edited from the horizon local_settings? There are obvious use cases for both situations where you want this to be dynamic or you very carefully want to protect which IdPs are available to log in with and from that perspective it would be a very unusual API for keystone to have. 

My understanding of the current websso design where we always logged in via /v3/OS-FEDERATION/auth/websso/{protocol} was so that you would run a discovery page on that address that allowed you to customize which IdPs you exposed outside of keystone. Personally i don't like this which is what i wrote this spec[1] was for. However my intention there would have been to manually specify in the local_settings what IdPs were available and reuse the current horizon WebSSO drop down box.
