the "feature" is used, yes.  Some providers have customers in different 
RIR service regions.  Some organisations have address space registered 
in different RIR service regions. It's impossible to avoid in many 
situations.

What's important right now is to close off the option to create new 
unqualified as-set names, and to move the existing qualified non-RIPE 
ASxxxx:as-set objects from source: RIPE to source: RIPE-NONAUTH.

Denis was correct that this was a bug during the implementation of NWI-5 
(not ripe-731 which I mistakenly quoted).

After that, we can afford to spend a bit of time looking at potential 
clean-up options.  There are 1590 empty as-set objects.  700 of these 
haven't been updated in the last 5 years, and some going back 20 years.

I wouldn't lose too much sleep about deleting empty as-sets.  Contact 
people, set a timeout, and then delete.  Worst case, people can 
reference new, qualified as-sets.
