+  - question: What is the behavior change introduced by this PR?
+    answer: |
+      Behaviour is changed in three ways. First, as per the goal of this
+      PR, optional indexes are no longer wiped again when the node is
+      restarted before reindexing is completed. This aligns the wiping
+      behavior of optional indexes with that of required indexes. Second,
+      when a user requests a reindex through the GUI, this request is no
+      longer ignored, reversing a subtle bug introduced in [b47bd95][gh
+      b47bd95]. Third, the log line "Initializing databases...\\n" is
+      removed.

+
+  - question: What are the two ways an optional index can process new blocks?
+    answer: |
+      When an optional index is initialized, it checks if its highest
+      block is the same as the current chaintip. If it is not, it will first
+      process all missing blocks with a background sync, through
+      `BaseIndex::StartBackgroundSync()`. When the index catches up
+      with the chaintip, it will process all further blocks through the
+      validation interface using `ValidationSignals::BlockConnected`.
+    link: https://bitcoincore.reviews/30132#l-52
+
+  - question: How does this PR affect the logic of optional indexes processing new blocks?
+    answer: |
+      Before this PR, wiping the optional indexes without wiping the
+      chainstate means these indexes will be considered out-of-sync. As per
+      the previous question, that means they will first perform a background
+      sync before switching to the validation interface. With this PR, the
+      optional indexes remain in sync with the chainstate, and as such no
+      background sync is required. Note: background sync only starts after
+      reindex has completed, whereas processing validation events happens in
+      parallel.
