I disagree. Drupal's behavior is actually bad here, because
hook_flush_caches() is what we use when the 'clear cache' button is
pressed. The cache clear that happens during cron runs is actually a
misuse of the feature from its original intention, I think.

In any case, that wasn't really relevant to my point, which is that what
you're asking about is the Pressflow model of caching, and you should
look into it.
