1. The decision to make this change was made in the Admin Task Force meeting of 2024-03-04 as a fast-follow on the main Divisions PR.
2. The reason for making the change is that we couldn't articulate a good objective basis for favoring one translation over another as "primary" and felt that doing so could lead to unnecessary controversy in multi-lingual jurisdictions. We felt that it is a different situation than with the "primary" name of the names structure because the name of a feature is much more local and primary preferences should tend to even out, whereas with local_type we would want to be able to have a single "national" policy to make the data programmatically friendly. But a single policy would tend to globally prefer one translation over another so we decided to drop "primary" instead.
