What do you mean with the above? If I understand the line correctly,
then I disagree with it.

IMHO generally ones network infrastructure is pretty aggregated
internally already as the physical structure is most likely also a
star/bus topology which fans out towards the endusers, while the core is
where you connect to the Internet. When you have 'home users' and even
residential users they generally get connected to a PoP for a certain
neighborhood. Generally these users won't move around the country. As
such, just give the PoP a /40 or whatever you need to serve the users
from that site. This keeps the number of internal routes low. Now if you
have a well paying customer who wants to take their /48 along, just
announce the more specific in iBGP. Of course never announce a de-agg of
the allocation you received into eBGP.

Or did you mean something different?

Greets,
