Unless the same client hits the same server all the time this is a bad idea. Resolvers actually track capabilities of servers as it is the only way to get answers due to firewalls dropping legitimate packet and protocol misimplementations. Add to that different vendors / versions supporting different extensions randomly flipping between vendors / versions is frought with danger unless you take extreme care.
