Why not simply redistribute the whole BGP DFZ into the IGP?

Yeah, I remember.  But Babel doesn't have this kind of issues -- there's
no fragmentation, it's simply sending multiple independent updates, one
for each prefix.

We once redistributed the whole IPv6 DFZ into babeld, and it simply
started dropping routes when it ran out of table space.  (Table space is
artificially limited in babeld in order to avoid triggering the Linux OOM
killer.)

That's not to say it isn't a worthy experiment, just that it's not likely
to show anything interesting in the case of Babel.
