Impossible to set different primary and secondary text colors in a color theme

Both textPrimaryColor and textSecondaryColor are mapped to the same variable @text-muted in https://github.com/xwiki/xwiki-platform/blob/0e3ec41cda7ac82f14e8cc092ff2e5f059ed1fc1/xwiki-platform-core/xwiki-platform-flamingo/xwiki-platform-flamingo-skin/xwiki-platform-flamingo-skin-resources/src/main/resources/flamingo/less/colorThemeMappingOutput.vm#L33, thus, it is not possible from a color theme to set different values for them.
