I was exploring this a bit, one thing that I think would be interesting is considering how to make it possible to animate the brush (e.g, gradient) in a performant way. We may want to consider a () -> Brush API or similar, as just a raw Brush parameter would be worse for performance

Add Brush to TextStyle and SpanStyle.
Brush is a more capable way of drawing shapes, geometry, and text in Compose, a superset of Color. This change brings Brush as a first class property to TextStyle and SpanStyle to enable drawing Text composables using Brush.
Fix:
Relnote: Added Brush to TextStyle and SpanStyle to provide a way to draw text with gradient coloring.
Test: Manual tests on Pixel 4a/6 Pro
Test: New tests

Description
Currently the text composable accepts only color parameters for the text. This prevents developers from rendering text with a gradient or even an ImageBitmap used as a mask. As an alternative, developers need to leverage lower level components to achieve the same effect with more effort:
