+/// Usage:
+/// - The payee will set this option and set its invoice route hints to use [intercept scids]
+/// generated by this channel's counterparty.
+/// - The counterparty will get an [`HTLCIntercepted`] event upon payment forward, and call
+/// [`forward_intercepted_htlc`] with less than the amount provided in
+/// [`HTLCIntercepted::expected_outbound_amount_msat`]. The difference between the expected and
+/// actual forward amounts is their fee. See
+/// <https://github.com/BitcoinAndLightningLayerSpecs/lsp/tree/main/LSPS2#flow-lsp-trusts-client-model>
+/// for how this feature may be used in the LSP use case.
+///
+/// # Note
+/// It's important for payee wallet software to verify that [`PaymentClaimable::amount_msat`] is
+/// as-expected if this feature is activated, otherwise they may lose money!
+/// [`PaymentClaimable::counterparty_skimmed_fee_msat`] provides the fee taken by the
+/// counterparty.
+///
+/// # Note
+/// Switching this config flag on may break compatibility with versions of LDK prior to 0.0.116.
