It's optimized for certain workloads around code collab, so for now we don't want to oversell it. It doesn't have to be coupled with Git, though Git is very efficient at synchronizing changes. The protocol currently can be used for other things than a forge, but having an application influence protocol development is very helpful.
If that's what you've managed to pull off, that's like a way bigger deal than a p2p gitforge (not that that isn't super cool in itself)
I guess architecturally why does it need to be coupled to git and a git forge?
