As far as I know, all of the ongoing gender-free English country dances use a different system, “global terminology.” It’s based on current position rather than role, and so doesn’t have to use a substitute for gents/ladies. There are a small number of dances for which it’s awkward, though I’ve had callers present me with something they couldn’t figure out the global terminology for and I’ve usually been able to, usually resulting in easier teaching and calling than the gendered version. There was one ongoing contra dance decades ago that used a similar system.
