They did think about the transition path:

http://nislab.bu.edu/sc546/sc441Spring2003/ipv6/transition.htm

in order to "Deploy more recent technologies" listed here:

IPv6 packet design HAD to be different from IPv4 packet design, hence,
lack of backwards compatibility.

Don't worry, the sky is not falling, the Internet will not come
crashing to a halt, as some are suggesting.
