apprun VS elm-canvas

You can find the source code here and the compiled code here

You don't need native code to be productive in Elm. Elm is perfectly useable without it. Use of native code was not widespread before 0.19 anyway.

I would know. I was working on a large native code project that was killed by 0.19. It sucked for me that my project could not continue, but, I can't say that it has made much of a practical difference when it comes to making software applications. My project was called "elm-canvas" and it was about providing canvas support. Since 0.19, other people have found implementations of the HTML canvas element that do not rely on native code (Like Joakin's great 'elm-canvas' https://github.com/joakin/elm-canvas). For my own HTML canvas based software projects, I have been able to find my own non-native code implementations that work pretty well.

So, I think I faced a disproportionate amount of this problem, and I can't even say it has made much of a difference to my own productivity in Elm (and I have written a lot of Elm).
