There is nothing in the NEC that requires AFCI protection of the kitchen SABC circuits, assuming that they only serve the kitchen. There are other rooms that require SABC, but there is no requirement that these other rooms be served by the same SABCs that serve the kitchen.At least one of the SABC for the kitchen has to be AFCI protected. Any one has been cited not doing this?
Assuming the SABC serve the kitchen only.
But according to 210.11(C)(1) & 210.52(B)(1) the SABC must serve the dining room and the living room which are rooms included on the list 210.12(B).
So if I have only two SABC then one of them has to be AFCI protected? Do I understand it incorrectly?
If you choose to only have two SABC and you do have a dining room - then yes the one serving the dining room will require AFCI.
I don't know where you come up with the living room being a room required on SABC. Living room is not in 210.51(B) or permitted to be on with those circuits.
I am sorry the living room is not on the list. I was more thinking in terms of similar rooms so living room came to my mind.
So, at least one of the Kitchen circuits has to be AFCI.
Let's just say the kitchen circuits do not have to be AFCI, but if they are to be on same circuit as dining room they will be AFCI.
But one of the SABC has to serve the dining room doesn't it?
Two SABCs is the minimum...... not the required amount. You can use two SABC's, but if you do, then one must serve the DR and must be AFCI'd.
You are allowed to install 3, 4, 5, 6, 12, 41,..... 952 SABCs if you like. Only those that serve the dining room are required to be AFCI'd.
If you choose to run 952 SABCs you may find that you need to increase the number of breaker spaces available in your service.

If most heat generating kitchen appliance's use more than 50% of a SABC then why would you only install 2 circuits? You should put min 3 SABC , one for refrig and a seperate one for dining room (which needs to be on AFCI.)

We are also gambling that people will not use every appliance they own at the same time. There are times when that that will be wrong, there are also other people that will not even have enough appliances to overload two circuits if they did use them all at same time. Plus heat generating appliances generally either cycle while in use or are a short cycle use design (like a basic toaster).
So unless you have a kitchen large enough to have several cooks using it at same time - two circuits is quite often plenty of power. This is for dwellings only. A family that throws together a big Thanksgiving or other big parties could have higher demands, but this is likely only a problem a few times a year and not every day, but a good designer will make it work for them.
Sometimes you just cannot win.
I remember a church kitchen I wired.... put 9 receps on 3 circuits down the long c'top. They went 1-3-5-1-3-5-1-3-5. As soon as they started to use the kitchen, they started tripping breakers. Seems they thought plugging coffee pots and roasters into every third recep would be a good idea.
