Add requirments section for de-duping between services.
@@ -20,6 +20,11 @@ Requirements for this proposal are:
* A user should only have to agree to each version of each document once for
their Matrix ID, ie. having agreed to a set of terms in one client, they
should not have to agree to them again when using a different client.
+ * Documents should be de-duplicated between services. If two or more services
+ are hosted by the same organisation, the organistation should have the
+ option to give their users a single document that encompasses both services
+ (bearing in mind that the user must be able to opt-out of components of a
+ service whilst still being able to use the service without that component).
