Here’s an off-the-wall idea that you can either mull over or laugh at over Christmas (whether or not you celebrate it): Instead of labeling RFCs with a single adjective (that may be ambiguous or easily misunderstood), why not instead label RFCs with a directive about what we want readers to actually do with its contents? E.g., - This protocol is insecure; do not implement it - Do not implement this version; refer to an updated RFC instead Ross.
