Exception handling is necessary to efficiently support languages that need it without giving them direct control over the stack. I'd prefer if exception handling was provided with a more general abstraction though. GC is necessary for the same reasons, to prevent each language from bringing it's own GC and to enable cross-language interop. JIT is already implied by the very nature of Webassembly being an architecture independent stack machine, so every runtime has to already be a JIT compiler anyway (except interpreters). Exposing JITing to Wasm code is a natural progression and very valuable. Not that the WASM spec work doesn't have problems (looking in as an outsider), but the existence of these features are not my complaints.
