You say WireGuard was designed “for a different use case”.. that’s an extremely cryptic (buh dum tiss) thing to say. Do you seriously envision Mullvad or other VPN service providers adopting your protocol? At face value, I will conjecture and come from pessimistic point-of-view: this more of a niche feature of your product, appealing to a type of techy mindset where shiny new tools are somehow better.. which is playing with fire when it comes to encryption for privacy..
For anyone reading this, don’t listen to anyone here. Just go to https://privacytools.io and use those providers.
I would love to see Lightcore and ExpressVPN listed on that site someday.. good luck
