That's a bug in those ports IMHO. And that's the reason why this  
feature is not enabled by default.

"Not a good idea" as in "is not usable yet" or as in "it should never  
be the goal to be usable"? If it is the former, I agree (see above).  
If it is the later please elaborate (having correct dependency  
information should always be a good idea, I think the benefits are  
obvious, aren't they?).

Bye,
