Because it's been here before the formatter and will be here after it. I don't think there is any support for any formatting tool, except the general act of formatting for every formatting tool. And if you find your config has multiple lines just to format languages you've touched, then it's time to build a plugin or search for one. And if you find it, and it's quite not like you want, extend it as most plugins are open source and free.

If the tool doesn't suit you, build your own or find another.
