I agree. It's clear that IPv4 isn't going away any time soon (e.g. https://www.internetgovernance.org/2019/01/04/is-there-hope-for-ipv6/). Bringing beneficial features into IPv4 from Ipv6, like the aforemention extension headers, could promote uniformity between the versions and might help to facilitate transition to IPv6.
