WXR unnecessarily includes all post authors
|Reported by:||johnbillion||Owned by:|
If you're exporting just one post type (from Tools -> Export), the resulting WXR file still includes all authors from the posts table, regardless if they are the author of a post of the post type being exported. This can be particularly noticable for Pages (which are often only authored by a small number of different users on the site) and for custom post types.
This means when you subsequently import the file you'll be asked to map a complete list of all authors from the exported site, even if they have no posts in the WXR file being imported.
