 =======
-Pending

+**Deferred** as of September 2023.

+The goals described in the ADR are still relevant to future development,
+but for the intial launch of Blockstore-backed content libraries,
+the existing ``library_content`` block will be used instead,
+and it will continue to copy blocks from Blockstore into Modulestore as necessary.
