For that purpose, in the mind of the user, it does the same job as 'by

Those "quirks" are a rich source of confusion and bugs for anyone
who
doesn't understand how this stuff is actually defined.  (Yes, I'm
acknowledging, yet again, that the way C specifies its treatment of
arrays is confusing.)
A user who thinks that arrays are simply "passed by reference" is
likely
to try to apply sizeof to an array parameter (and might or might not get
a diagnostic from the compiler).  A slightly more sophisticated user is
still likely to be unsure of just where the "quirks" are.
What have you ever done to help make that kind of error less likely?
What is your goal?

 And that statement was incorrect, even with the "Although".
