Nope, Europe's always been bolt-country, the US has long been stud-country.

You could argue the other way 'round too, a thread-cutting operation is
comparatively expensive compared to boring a hole.
It's really a non-issue there, because once you add up the whole parts
count and cost the automaker is just telling the supplier "We want this,
done this way, and we'll pay this much" and the hub comes through the
door either threaded or with studs in it.

Maybe true in the US, but seasonal wheel swaps are probably more common
elsewhere.
