In this MR > https://gitlab.com/gitlab-org/gitlab/-/merge_requests/65178, the ~frontend is manually sorting the data. As the response from the namespace request is unsorted.

The question here is should the sorting happen on the ~backend instead (that way we will have a uniform and consistent data display throughout the app and the ~frontend won't have to worry about the adding an additional layer of sorting whenever we call fetch this data)
However! maybe we want to keep the sorting on the ~frontend for the flexibility. There's a possibility that we may not want to sort it by `name` but instead `full_name`. So sorting on the ~frontend would give us this flexibility.
