Comment (by ericlewis):

 @SergeyBiryukov said:

 > Seems like '/%postname%/' === $wp_rewrite->permalink_structure won't
 catch a static prefix, e.g. '/blog/%postname%/'. Would that still cause a
 conflict if there's a 'Blog' page with subpages?

 I've created a plugin to approach the problem in a more holistic way —
 [https://github.com/ericandrewlewis/wp-cool-slugs Cool slugs]. It uses the
 rewrite API to determine if a URL namespace is already occupied. This has
 the potential to avoid all problems of this nature. What do you think?

 cc @boonebgorges, who also has a natural affinity to
 `wp_unique_post_slug()`.
