After discussion with @simskij an additional requirement is that the LogProxyConsumer should be able to detect if the Consumer charm is providing a Promtail resource and in this case the Promtail binary should not be downloaded from the release page. This allows for air gapped deployments.

@balbirthomas closed in #158 ?

Closing this since we have extensibility to add new architectures but are lacking binaries to do so. I created #163 to track upload of new binaries and update Loki library.
