In my opinion, the current mess with resolv.conf is a case of accidental complexity. I don't think there's anything wrong with disabling badly designed systems that aren't useful for the problem at hand, assuming the admin is managing an environment where none of those tools are actually needed (which is not at all uncommon in a enterprise setting).
