Well... really if they are so valuable and you are criminals, you can cover your bases by running hostage (so long as it is a connection). This is what I typically do in my Andromeda deck as it allows me a lot of freedom and Hostage adds consistency to my deck.
Out of Crims, Hostage is a worthy nod if you feel that Katy or Pro contacts are so valuable to your deck that they need to get played ASAP. I would say even cutting one of the x3 for a Hostage adds more to your deck than simply running x3 and in some cases you might actually gain something by running Hostage. For instance, you could cut down to x1 Pro contacts (it has a really high install cost after all) and run John Masanori in the free slot, or one of the numerous other connections.
Basically, I agree with Arkhon. As more connections are printed, I think Hostage might be a more and more worthy addition, which will save you deck space and still maintain consistency in many, many decks that will be using either Pro Contacts or Katy (so MOST competitive decks at the moment).
