This is really what I was trying to get at. I used to work for a company that made a web app that needed to run on Windows and IE (it was very "enterprise"). The developers were virtually 100% Mac and Linux users. I don't think there was a single developer who actually used IE for anything other than testing features before code was merged. We definitely were not going to use IE-specific features, no matter how cool they were, because almost no one could actually run IE except in a crappy VM.
