Apologies but this does not address my main concern: most warnings we have today will likely become much longer. Would you advocate for long warnings if every unused variable warning comes with one or two extra pagraphs? Or if errors in guards comes with a list of all guards? It feels people are advocating for long warnings based on their experience today but this experience will no longer be true once we have catalogs. Today warnings were written to try to balance between too little and too much information, which may end-up not pleasing newcomers nor experienced developers. Once we have catalogs, the amount of information is much more, and showing it by default will be overly distracting.
What would be the difference between a short, medium or long warning? It seems there is an impression that a catalog means most warnings will become useless by default but that’s not the case. Even with a catalog, every warning will still provide enough information to be addressable on its own.
