What is the motivation for this?

I added this so that we are not blocked by the intent to ship. However, there
has been movement in the thread so this is no longer necessary (assuming jochen@
soon gives the LGTM3).

+enum CredentialMediationRequirement {
+  "silent",
+  "optional",
+  "required"
+};
 
 dictionary CredentialRequestOptions {
     FederatedCredentialRequestOptions federated;
 
     boolean password = false;
-    boolean unmediated = false;
+    // Defaults to false. This is not set here to detect when both 'unmediated'
+    // and 'mediation' are user provided, which results in an error.
+    [DeprecateAs=CredentialManagerCredentialRequestOptionsUnmediated] boolean
+    unmediated;
+    // Defaults to "optional". This is not set here to detect when both
+    // 'unmediated' and 'mediation' are user provided, which results in an
+    // error.
+    [RuntimeEnabled=CredentialRequestOptionsMediation] CredentialMediationRequirement mediation;
 };
