If so, what should be the values for:

Trial-and-error findings:

Is this considered a proprietary format that needs to be exported via Exported UTIs (UTExportedTypeDeclarations)?

Yes. While I couldn't find any explicit mention of this in the documentation, exporting the type was necessary for Finder to treat the directories as packages.

  • Conforms To (UTTypeConformsTo)

com.apple.package (source)

  • Mime Types (public.mime-type)

Empty. Directories don't have a Mime Type?

  • Pboard Types (com.apple.nspboard-type)

Empty. Pboard Types are deprecated?

  • OS Types (com.apple.ostype)

No clue.

Finally, does the Exported UTI identifier (UTTypeIdentifier) need to be the same value than the Document Type identifier (LSItemContentTypes)?

Yes, but I couldn't find any explicit mention of this in the documentation.
