+  Intended for use only by advanced users that clearly understand the tradeoffs.
+  I STRONGLY recommend that most users prefer the standard `freeze` since:
+    - The Nippy header is useful for data portability and preservation
+    - Compression is often benefitial at little/no cost
+    - The performance difference between `freeze` and `fast-freeze` is
+      often negligible in practice."
