Well written article, Peter!
I saw the Lightning reference in the footnote, but can’t figure out how you feel about the 4 major Lightning implementations. Do you believe we’d be better off with all Lightning development activity going into a single reference implementation?
Lightning isn't a consensus system, so multiple implementations probably do improve overall reliability.
Basically, my LN node can disagree with your LN node on most things without all hell breaking loose. That is not true of mining in a consensus system.

Absolutely. It just helps if you don't accidentally re-implement base layer consensus code in your Lightning node, when you're already using a separate base layer module (bitcoind) doing the same thing (but, correctly).

Exactly!
I asked a CLN dev, and apparently CLN just trusts your block provider to validate and does minimal further parsing. That's exactly how to do it right.
Defense in depth is ok in some circumstances where downtime is acceptable. But Lightning isn't one of those circumstances because if you're down too long your counterparty can defraud you.
