A lot of the progression on the Java language features occurred after Jigsaw (modules) shipped. From memory it was almost a decade of delays to pretty much every JEP because they couldn’t get Jigsaw and it’s underlying architecture right. I struggle to think of one modern use case for modules. Kotlin shouldn’t have happened but they let Java lang fester for too long.
