I've recently seen some recommendations to use hook_hook_info to provide "groups" to core-provided hooks so you can move your module's implementations of those hooks to $module.$group.inc. A poor-mans autoloader if you will.

Beware that such use is not in accordance with the API documentation which states that hook_hook_info should be implemented by modules declaring new hooks for other modules to implement.

In addition, having two modules on your system declaring a group for the same hook will break all use of $group.inc's for that particular hook. This happens regardless of whether the group is identical or not.

• DON'T use if all you do is implement hooks.
• DO use to declare own hooks that can be used in other modules.

NB: In rare cases, a module could implement hook_hook_info_alter to change a hook group, but this is again pretty hacky, for modules could still opt to have hook implementations in their main .module file.
