It's an educational project. No need to put it on blast over that. CE/EE students can buy a board for a couple hundred bucks and play around with this to learn.

A hypothetical ASIC implementation would beat a CPU rather soundly on a per watt and per dollar basis, which is why we have hardware acceleration for other protocols on high end network adaptors.

Personally, if I could buy a Wireguard appliance that was decent for the cost, I'd be interested in that. I ran a FreeBSD server in my closet to do similar things back in the day and don't feel the need to futz around with that again.
