Unless including a garage, there's no reason why a 2400sqm, which is 220m2 in the rest of the world, should not be 4-5 bedrooms.
We have two big bedrooms that we sleep in and two smaller ones that would be crappy adult bedrooms but are good offices.
I say all this because I agree, I think modern houses where people have fewer kinds and two adults work from home can have different and smaller "bedroom" layouts than traditional homes.
