-# Hack around a bug in prometheus_client
+# The last Python 2-supporting prometheus_client nevertheless tries to use
+# FileNotFoundError, an exception type from Python 3. Since that release,
+# prometheus_client has dropped Python 2 support entirely so there is little
+# hope of ever having this fixed upstream. When ZKAPAuthorizer is ported to
+# Python 3, this should no longer be necessary.
