Getting rid of scripts/batch files you can do if you generalize the erlexec binary a bit (in Docker for instance, as it was mentioned before, you perhaps want to be able to configure more things with environment variables for instance) but what would "statically linked" mean in the world of modules that load shared objects and even modules that can be upgraded? To statically link one would have to sacrifice the dynamic code reload, right?
