Re: I'm not an expert but I'm thinking "Not a chance."
Jason seems to be overly cautious, I've been running it on my Ubiquity ER-X and Android phone and this thing rocks. In terms of speed and stability, it leaves OpenVPN and the likes far behind.
What stands out most: enabling it doesn't involve any connection at all, zero battery drain. But when it notices you try to reach the configured network, it will pack your packets and send them off.
Since both Linus and Greg are a big fan of WireGuard, chances that it gets merged are the full 100%
