I also wasn't a huge fan of pin initially, but as it bounced around in my head for a while I really started to like it, for exactly this connotation reason.

They are meant as a temporary description of how these dependencies should be kept in order.  To my mind one "puts a pin" in something temporarily. To comeback to it later to do something with it at that time. Thus the pin probably does work with this concept.

I agree with everything here. :)
