+        <para>
+          Starting with 7.10.2 GHC would simplify both the left- and
+          right-hand-sides of rewrite rules, causing a variety of unexpected behavior.
+          Simplification of the LHS resulted in various rules to fail to fire (<ulink
+          href="https://ghc.haskell.org/trac/ghc/ticket/10528">Trac #10528</ulink>, in
+          particular affecting the widely used <literal>text</literal> library)
+          whereas rewrites of the RHS broke some of the more exotic uses of rewrite rules
+          (e.g. HERMIT, <ulink href="https://ghc.haskell.org/trac/ghc/ticket/10829">Trac
+          #10829).</ulink>
