The default privacy assurances of lightning are pretty decent so that's helpful, but I think there will be a need for on-chain privacy for quite some time, even for the average user. I like to see wallets adding payjoin fake coinjoins and collaborative transactions. I also like how Sparrow wallet has a toggle switch that either optimizes for efficiency or privacy, then automates the rest.

Automation is the key here though. If the default is shitty privacy, that's just what people will do.
