I think `cl::OneOrMore` causes a error to be generated if the option is not specified.
That would make it mandatory to have a  atleast one `--attributor-seed-allow-list` parameter for every invocation of 
opt

> The cl::OneOrMore modifier indicates that the option must be specified at least one time.
