Because it's a 46/36 which are chain ring sizes pretty peculiar only to CX. Road compact is 50/34.

Because they come with 'cross friendly gearing rather than road gearing.

36/46 chainrings? Classic cross combo.

There's nothing leg friendly about cyclocross 🙂

Leg friendly until you spin out on a 46 / 11 combo at 30mph... If you love super high cadence then go for your life.

IMO for real cross gearing the inner ring is too small and the big ring too big! I run 39/44 with a 12-27 cassette, having said that it very rarely touches the 39 anyway.

Agree with Blazin completely here, if you need a 36 then its quicker to run

No-one, you take a standard 130mm bcd road chainset and put your own rings on.
38/44 with 12/27 cassettes here as well.
