We are aware of this and have already in place Hysteria 2.0 for this exact scenario. More servers are being rolled out and we aim to make official update tomorrow.
You can already use Hysteria 2.0, as long as your client supports it (most of them). Simply update the subscription and you will get access to all Hysteria 2.0 servers.
I also want to remind that we have other protocols AmenziaWG, VMess and Trojan that could work just fine for majority of users.
Don't get your hopes up too much for hysteria2, http/3 is extremely unstable in Russia.
