- generics gains extra excluded generic "specialisations" (specifically raw types)
- java_properties stops overwriting the Java extractor's output, which specifically flags isDefConstructor which kotlinc does not
- types naturally gains a lot of new raw types
Pros:
* <obinit> no longer emitted: one less function per class
* Parameters to the primary constructor, if any, are no longer referred to out of scope
* Simple primary constructor `val` and `var` declarations work as expected
Cons:
* If there are multiple secondary constructors, no primary constructor and long init blocks, there could be considerable duplicate extraction of those init blocks. Hopefully this case is very rare.
