http://valgrind.org/info/platforms.html
It's not a better tool for developers working on platforms not listed there. In particular:
There are many platforms not mentioned here. Some are of little interest (eg. SPARC/*, */AIX). Some would be technically difficult (eg. IA64/*). In particular Windows is not under consideration here because porting to it would require so many changes it would almost be a separate project.
Note also
http://valgrind.org/downloads/
"Valgrind 3.8.1
...
For {x86,amd64,arm,ppc32,ppc64,s390x,mips32}-linux, arm-android (2.3 and later), x86-android (4.0 and later) and {x86,amd64}-darwin (Mac OS X 10.6 and 10.7, *with limited support for 10.8*)."
(emphasis mine).
Whether that says we should keep the canaries around is another matter, but it indicates that not everybody can use Valgrind.
