Overall I think Acinq is doing some great stuff - channel splicing, trampoline routine, bolt12. The one architecture piece that's missing is how to make it really easy to switch to another LSP and ideally migrate your existing channels. Something like greenlight may be the way?

And then something like the channel factories that @Super Testnet is developing to make it cheaper to get channels...

I think that will make it easier in some regards, but ultimately most humans aren't going to manage their own liquidity. This includes buying it from LSPs. Even though that is easier, most won't do that.
