My lightning is not custodial and works perfectly as well. To me, the rug risk is worth setting up a sovereign solution.

Custodial solutions are fine. They are better than fiat custodial solutions because the ability to instantly withdraw your money keeps providers very honest about their real holdings. They offer some convenience over self custody, and for small amounts that trade off makes sense.

My question is, what do you not like about the LSP model as demonstrated by Phoenix or Zeus? I think that having a single channel with a trusted provider who manages your liquidity is the best of both worlds. Self custodial, but very easy to onboard and manage.
