+# - Skipping B101: doesn't like 'assert' to check for condition.
+#   Reasoning: we do not perform code optimisation and thus this should not apply.
+#   See https://bandit.readthedocs.io/en/1.7.5/plugins/b101_assert_used.html
+# - Skipping B404: doesn't like 'subprocess' module.
+#   We use it to run shell commands. We should emphasize to developpers its weakness.
+#   See https://bandit.readthedocs.io/en/1.7.5/blacklists/blacklist_imports.html#b404-import-subprocess
+# - Skipping B113: request_without_timeout
+#   This rule adds a lot of noise to the results, is not a security issue and not something we want to improve upon ATM.
