We use this module only on the server side, and in most cases that is best practice. Front end use cases exist, support for that comes from the community so I've flagged this as "seeking contributions." It is not a bug as the code functions as designed.

The annoying warning originates from the postcss plugin. Here is a suggestion to ship postcss as ESM which would potentially fix it: postcss/postcss#1858

Alternatively exchange postcss plugin.
