This reverts1ed4e584f3. This reverts https://github.com/systemd/systemd/pull/18638 Keep .clamp_feature_level_servfail name, as imho it is more descriptive than just .clamp_feature_level, especially if we ever need to add similar workarounds as the one we had for DVE-2018-0001. However note that there is another retry which was added in8a33aa199d- seems to be working around Stubby resolver behaviour. Fixes: #26967
