We have some user scripts that checked this and used to expect true or false. It seems like someone has changed it at some point, but did not update the documentation.
The goal of this task is to:
- Identify the patch in which this change happened
- Understand the reason behind this change (it is not backward compliant)
- Ensure the change was properly communicated (e.g. through User-notice) and if not, do so
- Update the documentation on MediaWiki wiki
