I’d be interested in another cage match, if done well. I know Suzuki did one in AJPW and NJPW did some hell in a sell esque one. I know NOAH have done cage match recently too. Probably the most grounded gimmick match with a long history.
I feel like they have used KOPW to sort of test the waters for what stipulations fans find interesting. I think last man standing, I quit match, iron man match are examples of stipulations that can enhance a feud without feeling goofy. As long as they are used sparringly to preserve their impact, and not be a crutch.
