To this aspect specifically: AFAIU the client gets fed data that would
allow the reconstruction of the session from scratch (e.g. when being
sent to another IDP node that does not have the session in memory) for
*SSO* requests.
I.e., I don't think things are designed to restore the session on all
requests to the IDP, including SLO request.
