In Linux, if you are in userspace or are merged into the kernel tree, they won't break you. Otherwise, you can write your code but kernel upgrades can break your code. In Elm, it's the same but only a select few can get merged in. The rest get told to rewrite into "userspace" (pure Elm) and find their posts deleted or locked and are accused of being "hostile to Elm's goals". Oh, and you have to patch the kernel before it will load your modules, as it downloads from an official website and checks the Publisher field.
