Good throughput but it is only line of sight as that bw is in high frequency ranges.

2.4 ghz and 900 mhz are not "old" or "outdated." It's all rf spectrum. The lower frequencies are valuable for range/penetration.

We should weigh research on directed rf radiation higher. We can run a lot more devices with better UX if we can avoid blasting radiation in all directions.

In fact I'd like to see a wifi standard that utilizes the entire spectrum from 900 Mhz to 6 Ghz seamlessly without me noticing. If I'm in line of sight, switch me to 6 Ghz. As I move away, go to 5 Ghz then 2.4 Ghz progressively.

There are systems that try to do this today, but they are not seamless. The switchover is noticeable most of the times, and sometimes your device won't ever come back to the faster frequency. I suspect that is because the standard itself doesn't treat this behavior as a first class citizen. Manufacturers are building custom solutions.

What you described is exactly what WiFi 7 tries to do. We will see if it works well, if not WiFI 8 802.11bn will likely correct it. As with each WiFI iteration do.
