A shadowsocks inbound with a TCP HTTP header was dropped from Mihomo
subscriptions, although Mihomo's simple-obfs speaks the same wire format
(#6735). Such a node is now emitted with plugin: obfs, mode http and the request
Host header. Mihomo always requests GET /, and xray-core rejects a request whose
path is not one of the header's paths, so only headers that accept / map;
others stay dropped, as do non-shadowsocks protocols and the legacy Clash
endpoint.
