As you probably know, that's not usual the setup in North America, even 
for folks with electric ranges.

I've been responsible for bringing 3-phase into several new buildings. 
I'd totally endorse a VFC in most cases (except that it's one more part to 
break if that's a concern). The reason is that the lowest cost I've seen 
in Colorado was $4500 and the most is $7000 from Xcel. I've *never* heard 
of them simply saying "Oh your old transformer will handle that just 
fine." YMMV
