I started using v6 in the late 90s.
Software developed post-2000(-ish) should already be compatible. Unfortunately, there are a lot of developers that think this is hard/impossible (or they are lazy), and so we have software that is defunct by design.

Regardless of how the address was represented, software would still need to be updated.
They did. Every IPv4 address is in a reserved area of the IPv6 address space.
