Not AT&T systems maybe, but 4.x uses stdout to determine the device.
(Sys V uses stdin, so I guess you're right and V7 did as well).
Personally stdout makes more sense to me, in that you may well want to
pipe stuff into the stty command. What does V7 stty do if its stdin is a
file rather than a device?  Also, there's not much wrong with using stderr
for output if you regard it as being the `diagnostic' output channel
rather than strictly for `errors' only.

Matter of taste and what you're used to I suppose.  (Remember  Unix != Unix)

If you will let people fiddle with their operating system ...
