Hey. Totally valid concern. Honestly, I just like MASQUE, quic and new HTTP related RFCs in general. Cloudflare is a pioneer in this area and there isn't too much research in this area yet. My goal is to play around with it, provide proof of concepts and hope that it makes it to mainstream VPN providers and others in the future as well.

Don't know any other VPN provider that would implement Connect-IP yet.
