I was precisely focusing on LSP based non-custodial cause they are much more user-friendly compared to Blixt, OBW, Mutiny etc. ...

My hope for the near future is for custodians to implement a self-custody option within their apps based on the Blockstream Greenlight model. They could push for their users to take full custody all along the life of the wallet, while still allowing features only available on custodial wallets.

But yes for my family and friends they'd rather use my LNbits instance, or I could take the time needed to explain why self custody is important, and set them up a Phoenix wallet with good inbound.
