+# Upstream has switched to aiobotocore.  It's a huge hack that requires
+# a very specific botocore version, currently 3 months old.  Given that
+# boto* makes releases daily and various revdeps require newer boto3 /
+# botocore versions, this makes aiobotocore unmaintainable.
+# As a result, we'd be stuck with the old version forever.
