At this point there are countless issues about the formatting done by CodeSniffer. It plain out doesn't work in many cases, overrides format options that are contributed by other extensions in VS Code and does not reuse any of our AST parsing. For that reason, I am starting to think there is no reason to keep it in here until we have proper pretty-printing support from https://github.com/Microsoft/tolerant-php-parser that actually reuses our ASTs and can work while editing. For people who want to use CodeSniffer to format their code, there could be a standalone CodeSniffer language server (like there is a TSLint language server and ESLint language server). As said, we don't reuse our state anyway.
BREAKING CHANGE: removes formatting support
