I had a lot of hope for reticulum, but it's a one man project with a near burned out maintainer, taking on an absolutely monstrous task.
I'm now cautiously optimistic. This or something similar is likely the long term future of mesh networks, but in the short to medium term, meshcore is the way to go.
The protocol itself is more mature than the maintainer situation suggests. I built a complete independent implementation from the public spec in a few sessions. If one person can do that without touching the reference codebase, the foundation is solid. The risk is to Mark's implementation, not to Reticulum as a protocol.
