This also opens up the way to supporting new units through a polyfill:

1. Alias the original unit to its `--` counterpart, i.e.

    ```css
    @property --brm {
      syntax: "<length>";
      initial: 1brm; /* browsers with support will use this */
      inherits: true;
    }
    ```

1. Have a JS polyfill calc + set the initial value in case of no support

1. Use the custom unit throughout the code

    ```css
    height: 100--brm;
    ```
