As of right now, there are not enough people in any given zone to do these fates. Letting them provide a small number of allied seals would help bring new life back to the zones they are in and give new players a chance to participate in the sort of large scale fights that we used to experience at release. As of right now, these fates are mostly dead content.

It may also help those who approach getting seals more casually, as these fates are easy to spot and take a long time to complete even with large groups.
