   So that’s a “no”? You *should* continue to depend on critical   
   components which have become obsolete or unsupported?

   How is the customer supposed to do that? Are you able to offer them   
   solid support contracts for the duration of the expected life of the   
   product in question? What happens if that duration exceeds the   
   supported lifetime of some upstream proprietary product that *you*   
   depend on? Do you take on the necessary support burden on behalf of   
   your customer? Or do you just tell them that’s not within the scope of   
   the support contract?
