I think 2 is more about how a single wasm interpreter can host multiple "serverless applications" and execute them without the process (/language runtime) spawning overhead. > 95% of the advantage that docker has over a tarball is due to gcc's (and glibc's) strong bias towards dynamic linking and how hard it is to portably package a python application's dependencies. Mhm. docker, flatpak, snap, appimages .. so much complexity is basically us dealing with linux dll hell imo.
