Hey there.
The plan is to port it over at some point, but I don't have a timeframe for when. I haven't even tested to see how much changing from the MV version needs to be done to make it work in MZ at this point. I expect it should be relatively easy to port, since it didn't inherently rely on any of the yanfly plugins like the old MV Block Chance plugin did.
Sorry I don't have a better answer for you right now, I have a lot of things on the go at the moment.
