Environment variables are not necessarily a good thing to rely on.
I did load up my Virtual Machine (which has VS6, VS2003, VS2008, and VS2010 installed) to take a look, and I can see what you mean.
However, VS6 doesn't provide such a variable, and while I do realize that usage of VS6 is far lower than any other it's still a formidable force.
So a way that it useful on all systems, for all versions in use is probably best.
