Do LN implementations make it a priority in their coin selection code, to open channels without change outputs? I guess not, but I was just thinking that channel opens are a unique opportunity for consolidation, because you usually don't care about exact amounts. While you can say, reasonably, "nah, we'd prefer to have the channel open pattern the same as the payment pattern for privacy/anon set", the economics of utxos is going to be vitally important long term, plus removing change from a payment breaks some heuristics. Even more interesting ofc is if you could negotation a 2x no-change coinjoined channel open.
