Why is that a bad thing? 2.4Ghz gives significantly higher range at lower power than 5/6Ghz. Crowding of those frequencies isn't a huge issue for such devices as their bandwidth requirements are generally tiny. The best thing that can happen for these devices is for other (higher bandwidth) devices to move to 5/6Ghz and in doing so remove much of the contention that occurs on the 2.4Ghz space.
(Or move to protocols like Thread, but that's a completely different conversation - and even then it's still 2.4Ghz!)
