As you mention, it's a heuristic. If I had infinite time, I wouldn't use that shortcut. But alas...

You mention web designers--out of the dozens of designers I respect, I don't know a single one who uses Windows. Do you?

There is a difference between a designer and a developer. If you are hiring for designers why do you care if they can program at all. I know dozens of designers who couldn't write a hello world in Python yet have a beautiful web portfolio and yes some of them use windows.
