Would it be possible to add support for CSS Cascade Layers (@support)? This plugin would potentially handle ordering/scoping during compilation to provide the expected behavior of Cascade Layers in compiled CSS files if browsers indicated in browserslist do not yet support Cascade Layers.

I haven't given extensive thought to this idea, so if it just wouldn't work the way I described, then fair enough--feel free to close this.
