A general question first: Notwithstanding the discussion of how many use
it, do we agree that the combination of using shift-select-mode
_without_ permanent transient-mark-mode ("shift-select-mode-only
scenario") is a supported scenario in Emacs?
Because that's what this bug is about, in the end: Instead of
discouraging the shift-select-mode-only users to use rectangle-mark-mode
I would like to find a solution that helps them. Without affecting any
other users. Is that not a valid, probably even noble ambition?

It would be backward-incompatible only where the behavior currently is
confusing. For those who use permanent transient-mark-mode nothing
would change.
Another option, not featuring backward-incompatiblity at all but still
helping shift-select-mode-only users: Adding a rectangle-light-mark-mode
that provides the selection capabilities, but not the editing surprises
of rectangle-mark-mode. The documentation could then provide the
recommendation to use that new mode instead of the other.

I disagree here. Other editors do the equivalent of shift-select-mode.
I haven't seen yet an editor that (exaggerating) randomly activates the
region and then leaves it on until you press C-g.

Sorry. It would have the effect documented for `interactive':
If the string begins with ‘^’ and ‘shift-select-mode’ is non-nil,
Emacs first calls the function ‘handle-shift-selection’.
Function `handle-shift-selection' in that case temporarily enables
transient-mark-mode and pushes the mark, which in turn activates the
region-rectangle provided that RMM is enabled. The effect would be that
I can use the shifted cursor keys to select a region-rectangle even if
transient-mark-mode is not permanently on. Which I consider
advantageous.
