You could ask in that topic if a reverse method could be created, converting the inline style info into separate attributes (referring back to this topic).
One thing that sounds like a bug: While Inkscape reads the XML attribute, it does not change it, and just adds the CSS attribute with a different color.
This results in two different colors for the same object, making the color dependent on the order of preference a renderer assigns to these
Using Inkscape with Other Programs "fill" vs "style=fill"
Inkscape.org
Hello,
for an iOS app, I am trying to change the color in an existing file. This file uses `fill=#00bb00` to specify colors.
When I edit the file with Inkscape, this attribute still persists, and a new attribute is added: `style="fill:#ff0000`.
Browsers and the macOS finder see this `style` attribute, but neither Xcode not the iOS or macOS SDKs do.
Is there a way I can tell Inkscape to use the `fill` attribute?

Thanks for you help!
In a related topic, style info was converted to inline (opposite of your situation). https://inkscape.org/forums/questions/svgs-import-but-dont-display-correctlyfully/

Convert CSS attributes to XML attributes is an option in save as optimised SVG.
