Programs may output via exit code

Exit codes are to programs what return values are to functions, so it makes sense that exit codes would be allowed.

I disagree, this isn't necessarily printed anywhere meaningful. I think each challenge needs to explicitly specify that this is are allowed, or it shouldn't be allowed.

Real world programs like grep also use it, there is even a flag for grep, -q, where all other output is suppressed and the exit code is the only meaningful output. There are even programs where the whole purpose is to exit with a specific value, such as true and false

So this should absolutely be allowed.
