This is to avoid ugly tray icons becoming orphaned on such logout/system shutdown.

Is that really a major issue?
The problem is that VM tray icons windows aren't notified about "undock" event (when dock widget process is terminated). The proper solution would be to add such notification (so probably new GUI message). I'm strongly against GUI protocol modification for such minor thing.
Alternative some workaround would be adding some hook on tray manager termination (which is during logoff process) - probably via process watching tray manager selection, or some dummy icon. There is no clean KDE logoff hooks. And looking at the other KDE parts, there would be no guarantee about order of calling them.
I propose to close this as 'wontfix'.

Lets move it to RC1 for now, where many other GUI-related polishing is also scheduled.

It doesn't look to be easy to get logout notification, even for tray icons. Actual window manager process is terminated rather late in logout process, so simple hooks for WM-specific messages/properties doesn't solve the problem. Note that this behavior is the same on baremetal KDE, it isn't Qubes specific.
