The Elm people themselves worked with the impure browser api all the time. They just don't want me to do it. So it's not even a foolish consistency but just base gatekeeping. Turns me right off.

If you want to divide into two camps how 0.19 was received I'd say it's people who were maintaining a substantial Elm project on the one side and people who weren't on the other. Maybe if you're carrying a torch don't drop it on the ecosystem.
