stiffness of boost just isn’t required with wider rims coming out these days, I just ordered a 2017 bike, and 142 rear hub was in its favour over some other potential candidates, other pluses were thread in bb and space for a water bottle, simple things that ruled out some other bikes for me.
For previous bike purchases, standards were never really an issue, but I now have some pretty nice carbon weheels and they are moving onto the next bike so it had to be compatible, previous average wheels would have just been moved on.
