That’s a good point. There are also a bunch of grep commands that also spew out stuff that’s confusing and looks like errors. I’ve thought before about cleaning that up. It’ll likely take an hour or two and I’m somewhat reluctant to do it on my own time as most people are able to suffer through those scary messages.
Next time I make changes, though, (perhaps on the next month to make it easier to turn off the new ember-cli stuff), I’ll see about making that language less scary.
