Keep an eye on Dendrite development

[typokign]

Dendrite seems like it might be a useful homeserver implementation to support in the future. Synapse should still be supported, but running Dendrite as a monolith or as a collection of microservices may be a good option for those looking to use Kubernetes to horizontally scale their homeservers.

This would require pulling in a Kafka chart as a message broker, as well.
