I found that the styling process of an infobox migration might involve: That existing solution was because of only one theme being available in the output as a result. This was a constraint that would be well addressed with the above.
 * 1) repeating CSS declarations between infobox themes to ensure its maintainable
 * 2) merging the theme selectors for the same declarations in the CSS for brevity

I like the idea of having a second theme class, because it can allow wikis to code a shared theming for an infobox subset and also have unique theming specific to that infobox.
