I have a lot of very decent rims that were drilled for Shrader valves and it was not so long ago that more rims were drilled for this.
When mountain bike rims moved to being narrower the valve drilling changed to where Presta became dominant just as it is on road wheels, utilitarian bicycles still tend to use a lot more Shrader valves as this is something that most people are familiar with.
