QPWDLVL 4, new with IBM i 7.5

I was reading about the new value 4 for QPWDLVL.

Anyone using this?

I am seeing the following:
"A new password level was added to the Password Level (QPWDLVL) system
value. Password level 4 supports passwords with a length of 1-128 and uses
Password-based Key Derivation Function 2 (PBKDF2) with HMAC SHA512 (SHA-2
512 bit) encryption."

Considerations for changing QPWDLVL from 2 or 3 to 4
https://www.ibm.com/docs/en/i/7.5?topic=changes-considerations-changing-qpwdlvl-from-2-3-4

When the Password Level (QPWDLVL) system value is set to 4, IBM i Access
Client Solutions (ACS) version 1.1.9.0 or later is required to connect to
that system using ACS.

I ran this on our lpar with the most interactive users:
SELECT * FROM QSYS2.USER_INFO WHERE PASSWORD_LEVEL_4 <> 'YES'
Not one "real user" was on that list. Perhaps a benefit of requiring
frequent password changes. Maybe not a value you want to upgrade on day 1
of being on 7.5? But maybe 90 days later (or whatever your interval is) to
ensure most users have changed their passwords?
