I think most users were better off if you included only the longer
prefix.  After all, that's the one which is relevant for Internet
routing.  AFAIK, the current behavior is just a limitation of the zone
generation process.

I'm also surprised that your BIND process reaches 800 MB in size; my
own experiments led to a process size of 120 MB.  I used slightly more
compact A records, and the global table was a bit smaller back then,
but I would be surprised if BIND 9 needed more than 150 MB these days.
(Provided that you optimize the zone properly.)  However, this is
something the asn.routeviews.org operators need to do.
