Missing uninstall hooks and function calls

[Offereins]

Using 2.4, currently bbp_uninstall() creates a dedicated hook in core/sub-actions.php, but the function itself isn't hooked anywhere. It's only the phpDoc of bbp_activation() that reminds us vaguely of a former call to register_uninstall_hook(). Additionally the function bbp_do_uninstall has a similar problem, as well as bbp_delete_user_options. I tried to find any other 'uninstall' functions, terms or comments in 2.4, but couldn't find any.
I do not tend to uninstall bbPress, but I noticed when browsing the source.

Thanks for the reminder here. We'll probably try to work this into a future release (2.7?)

Ultimately, we may end up needing to go the uninstall.php route: ​http://codex.wordpress.org/Function_Reference/register_uninstall_hook#uninstall.php

Why can an incomplete uninstall procedure live on for two more releases? Can you explain the rationale behind those missing pieces and why not to fix it sooner?

Bumping all 2.7 to 2.8 milestone.
