Ours do as well, but essentially, that's because they are internal to
our network. Nobody would need that in the shared DFZ part, there I
agree with Rubens.

So although you would need the longer prefixes (right up to /128) in
your routing core, you would not necessarily have to have them in
your edge routers (as long as they don't directly connect to your
core, like Cisco keeps telling us we should do).

Dunno whether that's a feasible approach, probably not (big transit
providers essentially pushing transit through the core), but if
possible, it would lighten the routing burden a lot.
