Michael Jones:

The AAD team at Microsoft wants there to be a `logout_hint` parameter paralleling the `login_hint` parameter for authentication.  The language would closely parallel the `login_hint` description proposed by @{557058:62a79606-eed1-40c4-84ba-b8bff4291575} near the end of issue #1046 .  This is also closely related to @{557058:b8e41ea0-12ae-4d1a-9752-c2853862c3f5} 's suggestion of a `client_id` parameter, although more general.  \(@panva - maybe you can add a link to your issue as a comment.\)

They have situations where they don’t have the ID Token to use for the `id_token_hint`, but still want to specify the entity to be logged out - just like `login_hint` can be used to specify the entity to be logged in.
