is there a reason https://github.com/MeltanoLabs/meltano-map-transform isn’t on the Hub?

That’s a great question 😄 We’re planning for the Hub redesign to include it, but honestly we should be able to list it now. What’s odd about mappers is that they can’t really be used as a standalone plugin, so we’ve struggled a bit with the information hierarchy on where to put them. But not having it at all seems like the worst option 😬
