That may be true, but what would have been even better is never having the feature, as opposed to adding it, allowing many people to become dependent on it, and then taking it away. (Like everyone else, I'm not claiming Evan should not be able to make such changes -- just that making such changes will breed predictable resentment.)

This is a bad thing, presented as a good thing. Boring as it may be, if wrapping an existing piece of working code does the job with no downsides then it's always better to do that than reimplement it for reimplementation's sake.
Writing everything yourself is not innovation. It's busy work.
Sure it's a good way to learn a language, but when you just want to build an app why would you build yet another searchable select when there are more than enough JS options already available....

It has enable me to port the small kernel now to C++ for an Elm to native compiler.
Also, if you really wanted to bypass it and have your own kernel, that was always possible and not hard to do. Even in 0.18 custom effects modules could not be shared on the official package site.
