HOOK_theme() fits the criteria you outlined, except for one item: "It  
takes no parameters." HOOK_theme() actually has 4 parameters that are  
essential for theme developers. Of course, HOOK_theme() is a special  
case since themes (and not just modules) can call that hook. (And,  
btw, themes can't call the corresponding HOOK_theme_registry_alter().)

There might be other info hooks that could make use of parameters.  
Anybody know?
