Sass @import and global built in functions deprecated - plans to update library?

[Chewieez]

I get warnings in my Angular build for material-icons sass files related to @import and global built in functions being deprecated in Dart Sass with planned removal in Dart Sass 3.0.0.

Are there plans to update this library to move the Sass to the new syntax?
