I looked through the current version (7e6f5090) and you've got it to a good place, the launcher changes look fine.

The changes make me wonder if `-XshowSetting:aardvark` should be an error rather than default to print all settings. Something we should look at again.  Same thing for `-XshowSettings:system` on non-Linux, probably should have been a bit more discussion when that was added as its more about the container environment.
