By default, CSS includes the app authorisation mechanism (OIDC consent dialog) that #38 aims to fix.
The presence of this module allows any website in the world to request access to a user's pod, and if the user clicks 'Authorize' then this website gets full read-write access to all the user's data.
However, one could also probably configure CSS without this dialog, thus removing the need for both #38 and #64.
One could then use a custom mechanism to hand out OIDC tokens to only a hand-picked list of clients, and this would make the server a lot safer (although of course, less versatile) to use.
