User-sysmaint-split not installed after update | qubes passwordless root is still installed

In “Kicksecure Doc: Point Release” it says:

Installing any version of Kicksecure 17 and fully updating it leads to a system which is (mostly) identical to installing a Kicksecure point release.

In “Kicksecure Doc: Sysmaint” it says:

Starting from version 17.3.9.9, Kicksecure comes with a security feature called user-sysmaint-split enabled by default (in Xfce and above).

My question is I updated whonix-workstation-17 and user-sysmaint-split doesn’t exist, as I explained above.

Also:

… and whonix news didn’t say

Surely the difference between the image update and the normal update is not only sudo apt install user-sysmaint-split && sudo apt remove qubes-core-agent-passwordless-root, then people who are new and installing with images will have pros than people doing normal update?

My question is clear: Do Whonix users who update normally get user-sysmaint-split installed and passwordless root removed automatically? Do we have to install the new point release from an image to have that?
