I recently found out about Apache Netbox that would act as the authoritative source of truth for the network topology and replace majority of aether.config.yaml. In Splynx, I did not see any mention of an external solution. It seems they have their own stack for that.
A better and UX-friendly implementation would have been Netbox + aether.config.yaml -> configuration pipeline -> topology.yaml + <other generated files>.
