If someone does not have a server that they can run actions to connect smart assistants like Google Assistant to their device, it may be good to just have Ristretto handle OAuth2 so when setting up the action, whoever is doing it can just point everything directly to Ristretto.
However, this would mean that Ristretto's public server would be exposed. Therefore, requiring port forwarding, using something like DuckDNS for a domain, this is really a scenario for which ecosystems do not allow for local servers to be used or if someone does not have access to another device to run their server on.
