Feature summary (what you would like to be able to do and where):
Support protection level defined in wgRestrictionLevels for MediaWiki:TitleBlacklist
Use case(s) (list the steps that you performed to discover that problem, and describe the actual underlying problem which you want to solve. Do not describe only a solution):
Currently we could implement some basic protection via TitleBlacklist, for example <noedit> to restrict edits to admins only, or <autoconfirmed|noedit> to allow autoconfirmed user to edit certain (set of) page(s). With more and more sites enabled some customized protection level, (i.e. extendedconfirmed, the most common one), I thought it would be great if titleblacklist could support them.
Benefits (why should this be implemented?):
More flexible restriction made via titleblacklist.
