From a technology and design standpoint it looks really good, and seems fairly priced for what you get. It doesn't really solve the 1x problem though, and the 9t cog arguably makes it worse. Look at the ratio chart below with the speeds most of us normal cyclist actually ride gravel at (8-20 MPH'ish) most of the time in the red box (Ekar top, GRX 2x bottom). If you like to pedal at a steady cadence, this is still makes no sense.
