Comment (by ericlewis):

 > 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?

 We can drop this into our logic for looking up a unique slug for a post
 (`post_type = post`). This would be complex to use for page slugs, because
 that query ensures uniqueness is tied to diffferent post_parent levels /
 URL path hunks.

 Do you think that's a must-fix use-case for this issue, or an edge case?
 This is not the only collision of this flavor we will see, e.g.
 `%tax_base%/%tax_term%` collisions with a subpage.
