P.S. Regarding Gregory's response (that came in while writing this) potential abuse is not really a concern. We have a block button.
Indeed.
The worst abuse that can happen is that vandals un-noindex libelous information, so that it shows up in Google.
But consider that as long as article space is indexed (which it should be -- we shouldn't put anything in the main namespace that we wouldn't be happy about showing up in Google) vandals will always be able to do just that, by adding the info to an article.
Our strategy for the latter tactic is to block those vandals; there is no need for stronger measures for vandals who tamper with no-index.
