and this is different from only carrying the 253 usable /8 prefixes in

The set of customers who have addresses under a given IPv4 /8 prefix greater
than 127 do not all aggregate into a single topological subregion (e.g., a
single ISP), and therefore more granular routes must be widely disseminated
to make those customers reachable. That's the difference.
No. This is a historical feature that IPv6 alleviates by being able to start
over with a clean slate. You could (at least theoretically) emulate this in
v4.
The difference is that v6 gives you the option of significantly more TLAs than
v4 can ever have. Of course, this isn't really a feature.
