That's what happens when you have an high level VM that wants to support high level concepts from multiple high level languages, and all your languages need to be able to talk to each other. Same thing will happen to Wasm as it decides to add more and more high level stuff “to avoid shipping multiple GCs” and “to get different languages to talk to each other.” As soon as you want to abstract over more than “a portable CPU and memory” you get into that mess. Never worked in the past better than JVM and CLR, but let's keep trying.
