This hasn't got to do much with security.

Uhm, sorry, obviously, you did not understand what I wrote, but I have
trouble phrasing it in a better way.  Here's another attempt:

If the TTY is owned and group-owned by the user, the modes 0600 and
0620 are equivalent (assuming per-user groups).  In order to enable
messages from other users, "mesg y" simply sets the file mode ot 0620.
However, if a per-user group is used (and not group tty), this does
not have the desired effect because programs which are SGID tty (such
as /usr/bin/bsd-write) still cannot access that TTY.  This means that
the warning is factually correct.  It makes perfect sense because the
"mesg y" failed to do what was explicitly requested.
