The IPv4-space is heavily fragmented because everyone runs out of their
allocated range all the time, to ask for a new and unrelated range. With
all historical mistakes and policy changes, the IP space has become
a mess.

IPv6 offers much much larger ranges and much simpler renumbering schemes.
The old mistakes are undone: enough ways to make new mistakes.
