I used variable modes to create "theme-tags" for Relume, basically just adapting class strategy for modes to Relume and it works really good in my initial testing. Like "theme-yellow"-tag uses a variable mode called "Yellow Mode" and when applied to a section changes the colors of the background, lines, buttons, borders etc. I just think this is such a win, curious about plans to make something similar natively integrated in the styleguide/cloneable?
