To illustrate I’ve a Lightning node, and wish to shut it down. All its channels have been closed, and its onchain pockets has been drained.

Is there any purpose why I would need or must hold some or a part of its knowledge listing round? If this had been a Bitcoin onchain pockets, a chance may at all times exist that somebody would nonetheless ship cash to an previous tackle, and therefore, I could wish to hold round its key materials without end.

My understanding is that this isn’t the case for a Lightning node, as all methods of receiving cash contain interacting with my node. Is that right, even when speaking current protocol enhancements under consideration? If it issues, it is a Core Lightning node.
