I know right? Who wants sub-millisecond readiness, sub-second image replication and a measly couple of megs worth of memory alloc per service when everyone can just get themselves a 2 gig springboot heap by default?
FWIW Wasm is hitting kubernetes because that's what customers are explicitly asking for, and the majority of enterprise Wasm-on-k8s afopters are doing so precisely because they want to eradicate Spring bloat and the associated supply chain risks from their engineering orgs.
There are plenty of supply chain attacks without Spring into the picture.
Also, are you sure you are talking about Kubernetes performance over there?
