These tweets[1] from Ben Cox who many of you might know really
highlights another issue with recursive as-sets. (Essentially, there
are as-sets that are recursively so big as to include more AS's than
exist in the DFZ. To me feels like you might as well just ignore the
filter entirely and just always accept in such a case.)

Hi Cynthia,

AFAICT this is expected and valid behaviour. There will always be more ASNs registered than actually being used. Also, there is no one DFZ view. It looks different in different parts of the world/Internet, some of the ASNs will be visible only in certain locations. This is normal operating procedure in my opinion.

Cheers,
James.
