In applications with entry points deserialized from snapshots, they don't need an additional CLI argument for the entry point script so process.argv[1] is going to be other user-defiend arguments. We could consider copying process.argv[0] as process.argv[1] like what we do for single executable applications, but for now just don't exapnd it so it's easier to backport to previous releases.
