"And why would one not want to have 0.7m horizontal accuracy while moving at 100s of knots?"

You probably need a lot better than that when you fly a SAR on a jet like the GlobalHawk.

Think Galileo, Waas, Glonass, and gps could give you more than 38 sats, over determination will give better results and much faster cold starts without almanac and assist. Waas helps a lot when you run on a Uav chasing bad guys, think timing under motion without position hold mode, so there are four parameters to find every second and waas does improve timing in that scenario. And why would one not want to have 0.7m horizontal accuracy while moving at 100s of knots?

Why not offer 50 Sats? Silicon doesn't cost anything anymore. Companies in china pay less than $8 for these parts in large quantity.

I think the quality of the results speak for themselves.. CNS verified the ublox timing is almost as good as the M12+ but with everything else vastly improved. Trimble soarly seems lacking so far. We would love to use a US made or at least US designed GPS but alas there are none so far. Waiting to be proved wrong..
