Rally America did pull the FIA 8856-2000 clause from their rule book for this year, but are rumored to be putting it back in for next year. Although, you'd probably know better than I given that you're part of that process, eh.
NASA has the 8856-2000 requirement in their rules, but are not really enforcing it. They are saying "get a new suit before the next event" at the moment. Not sure what they are doing for FIA listed events this year given that the FIA rules mandate that they require 8856-2000 suits.
CARS has avoided the subject all together and will probably continue to do so.
My point is more along the lines of don't buy an 86 suit expecting to be able to use it for the next five years. You might be disappointed. If you do go used, try to get one with an SFI tag on it so you don't have to rely on the FIA certification.
And I do hope you are right.

I have an FIA 1986 OMP suit that is still in excellent condition that I'm not looking forward to having to replace.
