I think selling people on lets all move to UtreeXO is going to be a tough sell, we also don't know how something like PIs and how cheap hard drive space becomes over time making the expansion of the blockchain not such an issue and if that will mean we have bigger blocks in the future

I also wonder how things will change with things like channel factories, making it easier to manage channels without touching the chain, Fedimint and LN channels on liquid, there is so much going on to scale bitcoin so who knows what wins or how these solutions all work together
