Most likely it's fine. Though it's not terribly difficult to set up some flavor of VPN so you're not exposing 22 at all outside your network. Personally I use Wireguard.
but you still have to expose something to connect to wireguard?
The benefit of wireguard^ is it runs over udp and won't respond unless a peer with the right key hits it. ie a port scan won't reveal anything because there's no tcp port open to handshake, and wireguard won't respond to junk data coming in.
^ Most VPNs run over udp. But i'm not sure say OpenVPN will respond to random crap, it probably won't but i don't want to state categorically that it won't.
thank you for the explanation.
