IIUC the parent's point is that if you first have to unwrap incoming, say, HTTPS traffic to obtain the Wireguard UDP packets, that unwrapping code might contain vulnerabilities, so an attack compromising the machine Wireguard is running on might occur before the packets ever reach the Wireguard implementation. From where I stand that's a somewhat academic scenario, though. (Unwrapping correctly & safely is usually not that difficult. Just don't use a memory-unsafe language for parsing & unpacking maybe.)
