Wow. That's pretty much every rule. I'll have to take a look at what changed in v15 and loop back.

[shannonmoeller]

Looks like this was intentional. Version 15 deprecates all style rules so this package will become obsolete in version 16.

https://stylelint.io/migration-guide/to-15#:~:text=Additionally%2C%20you%20may%20no%20longer%20need%20to%20extend%20Prettier%27s%20Stylelint%20config

If you're using v15 and are not making use of any style rules you no longer need this config plugin.

I'll update the README.

Great, thanks @shannonmoeller ! I'll remove stylelint-config-prettier from our configs and dependencies too.
