Wow, apparently it has, I just tried it here:

p34:~# smartctl -a /dev/sda | head -n 5
smartctl version 5.37 [x86_64-unknown-linux-gnu] Copyright (C) 2002-6 
Bruce Allen
Home page is http://smartmontools.sourceforge.net/

p34:~# echo $?
0
p34:~#

Normally you always had to use the -d ata parameter.
