If nothing is planned for the Mac version it should be fair to at least inform possible buyers of the uncertain future. Or that they only get some engine updates and bug fixes as for now.
By the way, the iPad version is faster than the Mac version, both running on my M1 Mac Mini. That got me by surprise, really.
I don't use the iPad version on my M1 Mac. That, I suspect, will end with a psychotic episode for sure.
