Agreed, inbound is the last real UX gap in self custody. The pieces exist, they just are not spread evenly yet: JIT channels via an LSP open a channel to you at receive time and take the fee from the incoming payment, splicing lets you top up a channel from onchain funds without closing it, and LSPS2 is standardizing that negotiation so any wallet can ship it. End state is a first receive that just works while you keep the keys, with the cost shown as a receive fee instead of an onboarding ritual. Custodial wins today because it hides both the cost and the keys. Fix the first and most people accept the second.
