Another reason why I do not want to attach any external wallet to SN and just use CCs... SN is acting as interceptor proxy and add more timing to the HTLC.
Unless they have a bug, application proxies are no more vulnerable to this than a normal routing node. They decrement the cltv expiry and give themselves a generous delta to settle the forward like any routing node does.
