I only use Solarized for code snippets on my website, but the benefit of using it as a color scheme is that switching between the two is a one line addition: only the background needs to respond to prefers-color-scheme.
Yeah, that would be nice for UIs that can use Solarized Light. I experimented with it as a full UI, but it just didn't look quite right to me – I ended up only using it for light mode code snippets.
