I had a look this PRs which, as stated above is indeed a clean backport (aside from copyright year) and according to its JBS issue, it was in fact  back-ported to Oracle's 8u291 release back in 2021.
Furthermore, I have checked that the entirety of the original content for this in patch is still present "as is" in the current JDK, which presumes it's not been found to cause issues since it was introduced back in JDK 13.
I therefore feel it is safe to integrate.

Regards,
Frederic
