FWIW I've got a niri IPC / bash / jq abomination that emulates run-or-raise functionality and works probably better than the original RoR. It cycles through windows matching a particular appId and starts one if one doesn't already exist. That, alongside rofi(wayland) as a fuzzy search nav for all open windows, made a huge difference to me.
I couldn't find a run or raise repo that'd have a ws.jq and I'm not convinced it's https://github.com/thaliaarchi/wsjq (whitespace programing language implemented in jq...)
Could you point at that?
