Hello Joe,
Long, long time no see.  Trust all is well.
I love the term "What does the Contract say?"  If your Customer is calling out 55110, then shame on them for calling out a revision.  Part requirements CAN'T call out rev: MIL-101.  [Approach politely]  You can actually go to them on that with full up DESC support.  I do full up 55110, 31032 and or 6012; no problem.  The MIL versions are more work relative to reporting -globally, not part number specific.  We continue to submit monthly most challenging builds for 55110 and continually update 31032 (more than monthly) to ensure compliance to letter of the law (literally).  The 6012 Customers with failsafe environments get the same product; actually more stringent... especially the Class 3 and the Class 3A.  
As a Consumer that owns a half dozen computers and family in the Armed Services, all the specs are great.  
Yes, I would vote to see 55110 (and 50884) go away; however they DO have their place.  The time to argue part compliance to appropriate specification is before parts are in hand.  I trust the other fellow is back from vacation and the issue is at his feet.
The MIL-PRF-55110 and the MIL-PRF-3102 and IPC-6012 are all alive well; I love these gosh darn PCBs... or is that pwbs.

  Our PWB expert is out on vacation, and I'm being drawn
  into a discussion with a customer about 55110C.

  We've moved to 6011/6012 for rigid boards, but I'm not sure
  exactly how we've documented or justified this change.

  My understanding is that the Mil spec has changed
  into a PRF, currently at Rev. G, and it's a practical
  impossibility to comply with 55110C because DSCC has
  gotten out of the business of administering the requirements.

  It would be great if I could show the customer a cancellation
  notice for 55110 that points to the IPC specs, but I can't 
  seem to find one.

  Can anyone illuminate the trail please?
