- should target `unstable` branch of `nimbus-eth2` - it looks like all the non-`gitmodule` changes are artifacts of this

Not in great condition, but doesn't hurt existing code either. Better given time constraints to merge this and improve it from `unstable`.

Is this just the doppelganger? That's intentional. Does `--doppelganger-detection=off` work?

Nimbus doesn't use doppelganger protection on sync committees because they're not slashable.

Agree with @dapplion that this would be a good addition.
