Okay, I understand. Thanks for explaining. I spent a lot of time on getting unsupported WiFi capabilities out of my E8450, to be able to use AX mode without being limited to single digit upload speeds on Apple AX capable devices: [Solved] 802.11ax worse than 802.11ac with mt76 driver? To agree on this and fix the performance bug created by unsupported modes took over one year.
Maybe you are right that this time enabling out of 802.11n standard modes is only a benefit and does not produce problems. For me this is an argument to not buy GL-MT6000 at this time.
