Most often two USB ports are only used to connect a keyboard and a mouse anyway.
Ah! But if you use the Official RPF keyboard and plug the mouse into the keyboard's hub, you only need 1 USB 2 port, leaving the other for any medium speed device you might want to attach.
that's a big if..
Likely the majority of people have some old keyboards and an unused usb mouse they might to reuse.

Well i dont see a reason for a Raspberry Pi to do and handle more than 480Mb/sec (or 60MB/sec) transfers. Nor do i see the reason you need a Raspberry Pi to handle the full speed of USB3 (5Gb/sec or 640MB/sec). Whats the idea to build something that have a function you never going to use to its fully potential anyway
well, you might not see it, others might see it. I didn't saw a reason to buy a RPi3b+ cause it was IMO broken by design. I don't have the numbers but likely millions of people saw it different and bought one. Maybe the 3b+ was for their purpose the perfect SBC, only cause you (and for the 3b+ I) didn't saw a reason to have it doesn't mean there's no reason to have it.

If USB 3 is backward compatible, why does anyone in the world bother with USB 2? Shouldn't all USB ports just be USB 3?
Maybe BOM costs? 4 good quality USB3 ports are for sure more expensive than the 2x2 mix (and a crappy USB3 connector is just a nightmare). Routing on the PCB might be tricky as well (who knows, I'm not an expert here but the fact they swapped USB and RJ45 is an indicator that routing wasn't as easy). On the first lock the balance between price and what you get looks a way better than the last two iterations (I still don't care about HDMI, my stuff runs headless (once again, different people different use-cases), but GbE over RGMII separate from the whole USB stuff was a good pick, finally GbE landed on the RPi not only 'by electrical characteristics' - sorry @jamesh, I had to comment on that
). For me, the most interesting part is the increased horse power with 4xA72 combined with GbE.
