Bug Details & Steps to Reproduce

We're subscription to the gossip of nodes so get a sense of the graph. We were using a btcd backend before but migrated to a neutrino backend with the default settings.

When reading the documentation about the supported LND backends, it wasn't clear that neutrino using their defaults had some limitations in terms of graph data. We were seeing channel gossip without outpoint and capacity.

After checking the lnd.conf, we saw the setting neutrino.validatechannels.

I would like/expect to see the tradeoffs between using the defaults on the available backends here: https://github.com/lightningnetwork/lnd/blob/master/docs/INSTALL.md#available-backend-operating-modes
