> 1. What is a recommended amount of subscriptions per channel?

Channels are just integers on the wire and a little bit of state on the
node you are connecting to.
It's unlikely to cause any issues.

Error handling is per-channel so it's a better idea to have one channel per
consumer than multiple

> 2. Should we avoid having so many queues? (one queue per project design)

Only real workload will tell but generally on multi-core machines it is a
better idea to have more queues
than a few very heavily congested ones.
