A DESCRIPTION OF THE PROBLEM :
JDK-8294867 suggests scrypt, but yescrypt, which is built upon it, is more reliable and worth implemented.
yescrypt is adopted by Fedora 35+, Ubuntu 22.04+, modern Debian, modern Arch Linux, and CentOS Stream 10 (i.e. RHEL 10 in the future) as the default algorithm. I would not suggest this if JDK-8294867 had been closed as "Won't Fix" or not been opened, or yescrypt were independent on scrypt.
On the other hand, I have never heard that scrypt was adopted as the default password hashing algorithm in an Unix-like OS.

Here is why Fedora adopted it: https://fedoraproject.org/wiki/Changes/yescrypt_as_default_hashing_method_for_shadow

Ubuntu info: https://wiki.ubuntu.com/Security/Features
Arch Linux announcement: https://archlinux.org/news/changes-to-default-password-hashing-algorithm-and-umask-settings/
CentOS: See /etc/login.defs, or create an user, change its password, and see /etc/shadow in the official Docker image (quay.io/centos/centos:stream10)
