Can we remove this enum altogether? Including the value-to-string function? The
spec doesn't force us to expose a specific reason at all (beyond AbortError),
and it adds quite some overhead.

Done. I didn't like the enum either.

+// TODO(mvanouwerkerk): Consider abstracting these more instead of mapping 1:1.
+enum PushMessagingStatus {
+  // Operation succeeded.
+  PUSH_MESSAGING_STATUS_OK,
+  // Invalid parameter.
+  PUSH_MESSAGING_STATUS_INVALID_PARAMETER,
+  // Profile not signed in.
+  // TODO(mvanouwerkerk) Delete when this value is no longer used.
+  PUSH_MESSAGING_STATUS_NOT_SIGNED_IN,
+  // Previous asynchronous operation is still pending. Certain operations, like
