Unfortunately the ESLint rule does not enforce type imports. ESLint is mostly not able to parse Flow syntax, so we have to run everything through @babel/eslint-parser, which strips the Flow syntax. I've noticed in some cases (eg. Prettier) it is able to pass through everything including the Flow syntax, but in most cases it gets stripped

We should make sure to include the file extensions for consistency, but it does not affect much (except my ability to open files in vim by putting my cursor over the filename)
