It doesn’t even matter. The sheer disparity in vulnerabilities over twenty years versus one year is impossible to hand-wave away.
We are talking about fourfold more CVEs over a twentyfold reduction in time.

It really does matter. I don't know enough about this specific case, but multiple order of magnitude differences in CVE numbers are frequently explained by different policies towards finding and assigning CVEs in many many cases.
Absent more information the default should be to hand wave it away as probably such a difference. CVE counts are not a even slightly reliable metric.
Most of them are TOCTOU races or improperly following symbolic links. For example, uutils mkfifo(1) would create a world-readable and writable FIFO before using chmod(2) to restrict its permissions. Another user could replace that file with a symbolic link between the mkfifo(3) call and the chmod(2) to change the permissions of arbitrary files [1].
Other ones I find concerning are that you could also bypass '-- no-preserve-root' with a symbolic link to root [2]. Or by using paths equivalent to "/", e.g., "/../" [3]. Historically, GNU coreutils has been pretty good with symbolic links and avoiding TOCTOU races. The only notable one I can remember is a chmod(1) bug [4].
I agree with your general point that the number of CVEs is a useless metric, though.
