It's better if we are able to customize the user capabilities prefix. There are some advantages:

  1. Security improvement.
  2. Allow users to customize their multiple WP installations and share single user table & capabilities information without hacking the core script.

Right now the user capabilities prefix is always the same as the $table_prefix.

For user table sharing, some people have been practicing it. See this forum thread. We share a database, set different $table_prefix for each installation, define the CUSTOM_USER_TABLE and CUSTOM_USER_META_TABLE into the same value. The only problem is, we can't share the same user capabilities list since we can't set the prefix to other value than $wp_prefix. This could be improved if we add conditional statement to see whether the capabilities prefix is already defined in somewhere else (e.g. wp-config.php).

  • Milestone changed from 2.8 to 2.9
  • Priority changed from high to normal

Moving to 2.9 for now as we are feature freeze and I don't want to change this now.

We need some more documentation of this and it would be good to review all the uses of $wp_db->prefix . capabilities as the one you have modified is not the only one.

You can set the $wp_user_roles global in wp-config.php, which will be used on all sites in the network. See WP_Roles::_init().

Having done that, plugins can still manipulate capabilites, but they won't be stored in the database, so you can pretty much do whatever you want.

So, being able to customize the cap prefix is unnecessary.
