production bikes are still coming with IS mounts because they can't control the location of flat mounts. And the facing tools available stink, including the vanishingly rare VAR.
I don't see IS going away soon, even though nobody actually mounts anything but an adapter to it.
The difference between a CX bike and a gravel bike is that CX bikes always had ridiculously small tires to make the sport more difficult. Can't recall too many CX bikes that would clear a 40mm tire, much less the bigger tires now commonly used on gravel bikes. Gravel riders aren't particularly interested in having flats, so they use bigger tires.
The industry took 5 or more years to actually understand the difference, I guess some people still don't get it.
