Yes! A huge part of the fragility of shell scripting is the fact that there are a billion options which change crucial semantics of how the language works.
Just pick some goddamned sane option values and disallow changing them!
There's a reason you don't see this kind of nonsense in "real" programming languages: It plays absolute havoc with reasoning about what will happen when you run a script. (You could easily miss the fact that the shebang line does/doesn't contain "-e" or that option to error-on-unset-variables is/isn't set, etc.)
