BlueWallet used to be like that until it became too regulatory risky for them to be the LSP, so they removed themselves. You are right in that trying to be everything leaves every user relatively dissatisfied. The current version of BW still has lightning functionality but it’s only for the advanced users.

I am just advocating have the wall between the two (simple vs. coordinator) an up-front decision point for users, keeping the wall between the two, but making the link through servicing each other a benefit to attract all users to the app.
