The things you mention are typically used by like-minded private groups looking for resources to improve themselves internally. You have little to worry about in terms of being called out for build or performance for public groups doing general content. Nobody is going to run into a standard level 60 dungeon and call out DPS numbers. They'd be quite likely to face penalties if they did.
If you're looking to advance beyond standard content you should be able to find plenty of players who are like-minded in terms of not wanting to take a metrics-driven approach.
