I'm still learning how to run my own Lightning node, so the operational side of this caught my attention more than the cryptography itself.

Removing a single online signing key as the main point of failure sounds useful. What I'm most interested in is how that feels in day-to-day node operation: signer availability, coordination, and how much extra complexity the threshold setup adds in practice.

If that can stay manageable without noticeably getting in the way of normal Lightning operations, it seems like a very interesting direction.
