No language in the PLT Scheme code base does this.  Unfortunately the first PLaneT language I looked at, Jay's datalog package, does.  Since I'm already 1/1 for PLaneT packages adding them, I'm going to stop looking there and just go ahead and change the code to only add the #%module-begin if it's not a single expression that already has one.
