My understanding is that many of them can be wired as 1, 2 or 3 phase at least in Nordic countries, though admittedly the ones which allow 3 are somewhat rarer especially when looking at stove top-only models (not combined stove+oven).
Thank you so much for sharing this. I learned something new today!
Almost every electrical network is 3 phase distribution, the matter under debate is if you bring every phase to each house, or if a phase reaches every third house.
Anecdotally I have never seen an electrical panel without three phases, but when I went looking it was like trying to find a source for the fact the sky is blue.
