its just a consequence of how utils does initialization, and how the types 
tool does scanning for type infos. it royally sux, imo. there really is a 
whole lot you can do about it without hacking on core stuff, afaics. one 
thing you can do which should work is gather up all the ftis that all 
subproducts and the product are going to register in one tuple, and then use 
that tuple for all the content inits. that should work, although in a dynamic 
subproduct loading scheme, its probably going to be a pain. basically 
something like this

#pseudocode
all_ftis = []

product_ftis = ()

def initialize(context):
   
   global all_ftis

   for m in submodule:
       sub_module = load_subproduct_module(m) 
       all_ftis.extend(sub_module.fti)

   for m in submodule:
       m.initialize(context)

   utils.ContentInit( fti=tuple(all_ftis)).initialize(context)

and have m.initialize  import back from the product to get the all_ftis and 
tuplize it.
