Searches are already slow. RetrieveAuthPage is also slow (and
even slower in the face of user-based authorization). Somehow I
think that performing RetrieveAuthPage for every page will simply
make the overall search too slow to be useful. Better is to exclude
pages from the search based on their name before they're even read.
Also, it's not always true that a site wishes to hide pages that
are otherwise inaccessible -- some sites like to let such pages
be found as "teasers" to other content.
However, I wouldn't have much problem with adding a $EnablePageListAuth
switch that uses RetrieveAuthPage instead of ReadPage for searches
and page listings. Let me know if anyone is interested.
