Wouldn't it be better to use Dmarc to protect the domain so that other email recipients are protected, i.e. people who aren't on your own domain and aren't using your domain's whitelisting?
I agree, DMARC definitely helps other recipients outside your organizations as long as they don't whitelist the domain. This video was primarily focused on if your own domain is whitelisted on the tenant, one of the unintended result would be a lot of spoofed emails getting delivered as it bypasses the content filter.
