Current IPQ 807X chipsets support Uplink MU acccording to QCAs own press release from 2017. As for enabling it and when is up to the manufacturers of the various routers/APs. A few devices with IPQ874 being WiFi certified state its support. I'm not sure its really going to impact your gaming much..... In regards to your ping spikes, could have an upload bandwidth contention issue which a QoS setup may fix, hopefully not some compatibility/hardware issue.I suppose upload mu-mimo is quite important if the plan for me is to use my wireless for gaming? Or are there enough improvements to shift when release 1 routers are out? My AC66U is not good enough in my new apartment with the busy network here (Tried both Asus Pcie-68 and DWA-192, both spike ones in a while which makes me think its the router)
I'd probably still wait a while till routers with more mature chipsets release though or at least the current crop of AX units mature firmware wise before taking a dive unless you want to be effectively a paying beta tester.
