We do, and from what we know a bigger problem in China is detecting traffic patterns. SNI filtering is not that big of a deal, in order to block your domain it needs to first learn which one you’re using. What for the traffic patterns, people in China prefer to selectively route traffic to the tunnel. For instance, the client apps allow you to route *.cn domains (or any other domains) directly. It makes it harder to detect that you’re using a VPN.
