Yes... Now that you mention it, I do remember the key in PDS
directories, but I never worked with those others directly. Do VSAM
datasets use disk keys?

No, SYSCTLG and CVOLs had key length 8, to say nothing of PDS directories.

Subject: Re: The Story of Mainframe Passwords
I remember that dataset. When I first started, one of my jobs was to
run a program someone had written that read every record looking for a
dataset match, and then spit out the password. That was for folks who
forgot their dataset password of course. The program took maybe 10
minutes to run, and one day I figured out it was probably the only
dataset on the system that used the K in CKD, so I reworked the program
to use the key and it could then find a particular record in an instant.

Including when password had nothing to do with authentication and system
access. The PASSWORD file (yes, single level dataset name) was used to
implement PASSWORD protection for specific datasets.
