It is ALWAYS easy to send an email with a domain that contains an extra letter and bypass DMARC. Lookalike or "cousin" domains are specifically not something it addresses. Keep in mind that is not always a bug. There are a lot of domains that publish DMARC policies, and it is unlikely that there are no other domains that are lexically similar and send their own legitimate mail.
