Because the author(s) of the Tool chose to do so...and, in my opinion, 
they should be free to follow either way.

A Tool doesn't get used, it sets up and changes the Environment...mainly 
by adding Builders or tweaking environment variables. At the time a Tool 
gets initialized, it's not possible to decide whether a provided Builder 
will get used or not.

The warning appears whenever you try to initialize the "msvs" Tool under 
Windows, without having a corresponding compiler installed. Setting 
"tools=[]" for all your environments would prevent this...
