+// Open questions
+// 1. I've re-used `TabInstance` from the public API, does that contain all of the information you and app developers might need?
+// 2. I didn't see any reason to add a `getTabs` function because `pages.tabs.getTabInstances`. Any reason that won't work for you?
+// 3. I've added an `AppTypes[]` param to `addAndConfigureApp` to allow for the host to show different app types to the user. Very open to changes.
+// 4. I've added empty, private `validate` functions for the threadId and TabInstance. Any validation that is possible will help prevent against
+//    bad data being sent to the host. If you have any validation that can be done, please add it there. If you *can* use restrictive types like UUID
+//    or something, that would be even better.
+// 5. I've made the namespace structure an empty `associatedApps` namespace that only contains the `tab` namespace. This was an attempt to leave room for
+//    expansion in the future for non-tab scenarios that will make it less likely that your callers will need to update their code. Open to opinions though.
