Try and have the code changed. In this case, maybe Scott Maxwell who used to be with ACI can help since he is one of the last honorable engineers out there.

Yikes.  Serious deja-vu here!  Even in the frozen wastes of North of 49, there are individuals (like some developers I have run across - I wish!) who haven't seen that connection yet.
E.g.  We can design in "plain" concrete, and our "residential" code allows (with no reference to the need to confirm by "plain concrete" design) top-supported basement walls up to 7'-6 1/2" with no mention of reinforcing.  It doesn't say, "Do not use rebar".  It merely doesn't say you must!  But if you do reinforce, then you must comply with the Concrete Code CSA A23, which immediately invokes minimum temperature and shrinkage steel etc.  That applies to walls as well.  And if you do some arithmetic then you will probably arrive at a required reinforcing content.  And, I've lost track of the number of times I have been asked why I keep putting rebar into foundations that John Doe has been building since Adam was a cowboy, without rebar!  Go figure :^)

Once upon a time I was trying to understand how the ACI 318 code was intended to apply to residential foundations.  So being young I called ACI and asked my question.  The gentlemen in Skokie replied that the particular provision in question was certainly not applicable since the 318 code had been written only for BUILDINGS, not houses. 

I then learned that if were to continue in engineering I would be obligated to reach my own profession conclusions as to code intent and recognize the reality that there was always going to be someone out there that would be of the opinion that I was wrong.
