The very important part is that no hook should be able
say that a page cannot be viewed. As for whitelists, I am not sure
it's efficient to pass a list of whitelisted items in every query:
WHERE ... AND (
xx_namespace NOT IN (banned NSs)
(xx_namespace IN (banned NSs) AND (xx_title IN (whitelist)
Instead of just "xx_namespace NOT IN (bannedr NSs)".
It would only need to be xx_namespace NOT IN (banned NSes) OR xx_id IN
(whitelist). See, those logic classes are good for something:
!p || (p && q) <=> (!p || p) && (!p || q) <=> !p || q
I shouldn't imagine that would be any less efficient than what you
currently do. You should probably look at EXPLAIN and see.
