Folder structure that turns `Page.md` into `Page/Readme.md` is confusing

In GitLab by @blacktav on Jul 10, 2021, 23:14

Creating a sub-document for an existing document converts the document to become a Collective with contents of the original document becoming a Readme.md in the new collective. This creates some strange behavior

• If the original document had a link from another document, the link continues to work
• but now creating a cross-link to the new Collective cannot be done i.e. Collectives cannot be linked to
• new Collectives created in this way cannot be reverted (versions)
• contents of a collective cannot be moved outside of its collective making problems above impossible to correct
• see also issue #174

No files, tests, or entry points are named in the issue. Start by reading issue #174 and the discussion here to establish the intended behavior for links, reverting a Collective, and moving its contents; done requires an agreed resolution for the Page.md-to-Page/Readme.md conversion.
