I cannot parse this sentence.

We could certainly declare hook_uninstall() to be mandatory for any
module that declares hook_install(); now that we have
drupal_uninstall_schema(), hook_uninstall() is usually trivial
(actually, it always was trivial).

For that matter, we could provide a default hook_uninstall() that
drops all the module's tables.  I think the new variable patch also
identifies variables by module so we could uninstall them
automatically as well.

This has nothing really do to with foreign keys, though.

Thanks,
