Just as most of us here do with accessibility, you'll have to sneak it in. You just write good code and just don't tell anyone (the first time you did, you got yelled at. That's a sign that if you are going to stay there, you stop showing people your code). It may take you extra time. Let them think you're a little slow.
I guess what you suggested is the best way, but despite my attempts to code well and bring it to their attention, they've been pretty indifferent about my code, they don't question it.
