Beryl 7 (dual-band WiFi 7 travel router) is also now available, which claims ~1Gbps Wireguard and OpenVPN performance, with a MediaTek CPU:

while it looks like Beryl 7 will launch with firmware based on a proprietary SDK based on OpenWrt 21.02, the fact that it's a MediaTek CPU and based on prior history with #GLiNet, the case is promising for future support for a version of GLi's firmware based on recent OpenWrt, and eventual mainline #OpenWrt support.
for what it's worth, WiFi 7 support on OpenWrt isn't exactly fully baked yet with other hardware either.
I'm very interested in this one, as I use Beryl AX freqeuently while traveling and it works well. I just wish Beryl 7 was tri-band... and available in other colors.
