i have a, possibly mistaken, model that the fetchers are few, content
and similar providers such as netflix, news and sports media, ... and
there are not many, maybe O(1,000).  and they make a pass once a week
or less frequently, as the data do not change much and their pushing
data out to their infrastructure is not frequent.

given O(10^5) inetnum:s with geofeed refs, and a sweep rate of once a
week or less, that seems pretty trivial.  the rpsl server damping could
dominate.

between the MUST and the example, i do not see the wiggle room you
fear.
