Oh, no doubt, this is clearly a rush job. While Intels's demo motherboards were rather nicely made (if entirely oversized and very difficult to fit in a case), the ROG one looks like Asus had a couple of weeks to make the design work. At best.
Just like Z370 was rushed to get 6-cores into the mainstream to compete with AMD's 8 (leaving what is now called Z390 (which was originally supposed to be Z370 and launched half a year later) as some weird in-between unloved stepchild), this seems like Intel realized a couple of months ago that they were probably going to compete with 32-core Threadrippers later this year, so they took a server platform, made the bare minimum of changes to it required to call it a consumer platform, and pushed it out.
At least AMD was forward-thinking enough to use their server socket on X399, leaving them room to grow. They also have an "advantage" in not needing the gigantic VRM required to OC these chips, of course. OC'd TR might max out at 300-ish W (though likely somewhat higher for TR2) , while these likely run 700-1000W at max clocks depending on chip quality. As such, X399 can have more sensible motherboard designs. Not that the same isn't possible for this platform, but people will probably whine when they can't OC their $2-4000 CPU on their $1000 motherboards.
