Future Style Guide Update: Text Colors, Better Shadows, & Dividers

In a future update to the style guide, will it be possible to format text with different colors? For example, you might want a heading primarily in black while highlighting some parts in blue to emphasize key points. Additionally, could a style guide component be created that incorporates tools like Better Shadows? Lastly, I realize this is a significant request, but can we include components or elements that feature dividers, such as diagonal sections or wavy designs?
