Description:
Currently it's not possible for templates like http://en.wikipedia.org/wiki/Template:Deletedpage to find out if they are transcluded on an unprotected page; such pages should probably be put in a specific category so that they are easy to find and fix. This could be done by having variables (maybe called {{EDITPROTECTION}} and {{MOVEPROTECTION}}) which hold the current protection status.

Pages are viewed much more often than they are protected. So the solution would be to cache it the same way as {{CURRENTHOUR}} is cached (i.e. recalculate it every time the page is purged), and to rerender the page when its protection level is changed (which shouldn't cause much extra query load).

I don't see why it would. Protection status is needed even now for the "edit this page" and "move" links (which are changed to "view source" and removed, respectively, when appropriate), so it should be already available for other uses.
In bug:16939, I indicated that variables {{editprotectionlevel}}
and {{moveprotectionlevel}} returning respectively the edit and move protection
level of a page, 'none', 'autoconfirmed' and 'sysop' would be extremely useful in protection tags. A recurring problem on Wikipedia is that protection tags are present on non-protected pages, because protection expired or it was not removed after unprotection. It is detrimental to anon and new users' editing. Currently, the only option to detect this is to add an expiry to the template, but this is largely unreliable and incomplete. Having those variables would make bots' work much more efficient and we could hide the template when incorrect.
Note that 'edit' and 'move' are just the default protection types. Technically, they can be removed, or added on to, so it would have to be something more generic, like {{PROTECTIONLEVEL:edit}}. I'm not quite sure how it would make work easier for bots, since bots generally read the raw page text or use the API rather than the parsed text, but it would be good for hiding the template.
Done in r45587. Use: {{PROTECTIONLEVEL:edit}} returns the edit protection level for the page its on. Will update documentation on mw.org shortly.
Great, thanks.
Having this variable will also allow to categorize pages with incorrect protection templates in specific maintenance categories that bots can patrol.

I've created a related bug 17354, on a magic word {{PROTECTIONEXPIRY:action}} returning the protection expiry for a given action.
