Why are KaMPKit/shared/src/androidMain/kotlin/co/touchlab/kampkit/*PlatformAndroid.kt* and KaMPKit/shared/src/iosMain/kotlin/co/touchlab/kampkit/*PlatformiOS.kt identical?* Doesn't this mean they could/should be in commonMain? Or does this mean I've misunderstood something fundamental?

Yeah those can probably be removed. There used to be more stuff in there but it's all moved into common over time. And I think stack trace stuff is in the common stdlib too. But note that even if the contents are identical, sometimes you still need stuff like that duplicated across source-sets, for instance if it's missing from JS

Err, yes... errr. whut? No, I don't understand. Also, since it's an example project it would be good to have something that does fit correctly there.
