I 100% agree with you. I think no one can specialize in all the things. Lightning has a very big surface area and there's a lot of different things you can do with it. Early folks had to build the full stack like you said, but I think we'll definitely see less of that. Especially as you think about how difficult it is to run an LSP from a capital standpoint. Not everyone is going to have the large amount of upfront capital that you need to start an LSP for their wallets. You'd have to have millions of dollars just to launch to your users.

As soon as we see LSPSpec adoption, I strongly expect the wallet app / liquidity provider roles to separate. We at Synonym do not offer liquidity services to US users due to legal constraints. It is our intended purpose to work towards a world where a wallet and LSP can be a separate entity so a third party LSP can provide liquidity to Bitkits US users.

I don't think liquidity is necessarily always going to be an interesting and complex problem for two reasons. First, the network will gradually become less dynamic as people who transact frequently will establish long-lived and maximally direct connections with one another. Second, tools, algorithms, and data will be available to help non-experts deploy liquidity in an increasingly effective way.
