Again I will point out, NEC 210.6 (A)(2) only applies to "dwelling units and guest rooms or guest suites of hotels, motels, and similar occupancies..."
It has no bearing on what you can do in your home. It only affects you in a hotel room.
There is absolutely nothing to keep you from installing a 240v receptacle in your kitchen for your European tea kettle.
Conscience may want you to put a GFCI on that outlet but 210.8(A) doesn't.
But isn't a dwelling considered a home? I guess the terminology might be off on my part.
