You're just confirming what I've said.
`C-h f C-SPC' tells you:
"When Transient Mark Mode is off, immediately repeating this
command activates 'transient-mark-mode' temporarily."
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
When t-m-mode is enabled, the notion of an
"active" mark/region has a meaning/effect.
When it's disabled, it has no meaning/effect.
The echoes you mention don't change this fact
(unless you consider those echoes to be the
only "meaning/effect). Those echoes didn't
exist before we added t-m-mode, and in the
case you cite they're just useless, at best,
or at worst (a wee bit) misleading.
T-m-mode is the default now (and that's a
good thing). And all of Emacs has pretty
much taken its behavior aboard, as a given.
That includes the echoing you cite, about
activation of the mark.
There was no such talk of mark activation
before t-m-mode was added. (There was only
setting the mark.) Why? Because there was
no difference in behavior active/inactive.
There was just no such thing as being
"active". And the same is true still, when
t-m-mode is disabled.
We can agree to disagree about this. (Or we
can just disagree without agreement that we
disagree.)
