I've met lots of conformation people who don't teach "sit". For some it's the belief that if you teach a dog to sit, it will sit in the ring, which is silly. For others, they are just spending so much time teaching the dog to free stack and gait, that they don't bother teaching a sit.
Watson learned to sit from day 1, and his default behaviors are sit and down. I rarely practice show handling stuff. The only time he ever sat down in the ring is during group when I let him do his own thing because he was young and bored and there were a lot of dogs in front of us, so he chose to sit or lay down most of the time. I'm not a brilliant trainer but I haven't found it hard to teach him that show lead + ring + judges + stand cue means stand up. Haha
