Why does load_csr fatal out when the domain list doesn't match?

return $self->_status(DATA_MISMATCH, "The list of provided domains does not match the one on the CSR.") unless (join(',', sort @loaded_domains) eq join(',', sort @list));

Why is it fatal to load a csr that doesn't match the list passed on the command line? Surely it makes more sense to generate a new CSR rather than just bailing out?

Would a PR for this be welcomed?
