Automated deletion of an account by waiting a year does not comply with the GDPR and your right to correct or remove your data. Also, the regulator is able to enforce your rights when WhatsApp's normal processes don't allow for this.
In my understanding, the context is that it's not clear whether it's your data really (e.g. no access to original phone number). IANAL, but it seems that proven ownership is a necessary pre-requisit for the right to be applicable.
