Project mention: The tar archive format, and why GNU tar extracts in quadratic time | news.ycombinator.com | 2022-07-23

Author of openat2 here, yes it would (as well as protecting against races where the target directory is having path components changed to symlinks during extraction). RESOLVE_IN_ROOT would be more akin to extracting in a chroot(2).
I've been working on a userspace library[1] which would make writing userspace programs that interact with these kinds of dangerous paths more safe (though it's been on the backburner recently).
