Most of the vets I've dealt with have asked at every appointment what is being fed (in case it may be relevant to any problems that are found), but don't comment on the food unless they believe it is having a tangible negative impact on the cat's health. All of them have been quick to promote prescription foods for medical conditions, such as kidney disease or urinary crystals where results are pretty well-documented. The more gimmicky foods such as dental kibble only really came up when there were free samples available, but never really pushed.
One clinic I went to employed a feline nutritionist, who provided consultations to those who did not want or were unable to use prescription foods for whatever reason. They usually tried to find commercial foods to suit the needs of the cat, but would also help develop home-cooked recipes if needed. No raw, though.
I've only met one vet who supports raw (my current vet), but she is weary of home-made raw due to concerns of nutritional completeness. She doesn't trust internet recipes, even those developed by vets, and is very adamant about meeting AAFCO standards. For the most part, her attitude towards food is to feed whatever works for both the owner and cat and is nutritionally complete. She doesn't seem concerned about ingredients, except where there are specific health concerns. She sells prescription diets, of course, but only prescribes them when no other food can offer the same benefits.
