Don't worry; WireGuard isn't going anywhere. The "virtual/wireguard" package was added mostly as a mistake a long time ago, was never intended to be an actual virtual, and has been in packages.deprecated for 8 months now, with large ewarns on every install. It's time to actually get rid of it once and for all.
The right way to install WireGuard is just `emerge wireguard-tools`, and maybe if you're running an ancient kernel also use `emerge wireguard-modules`. So this is an announcement for a quick last riting of virtual/wireguard, which was meant to sail away a long time ago.
