Ordinarily, warnings come with a link to the message in question, so your main suggestion is more or less there.
There is a small UI bug which makes this difficult to do on mobile and sometimes forces us to issue a "generic" warning, so on rare occasions this information is missing. That will be fixed Soon™️.
In addition, we normally follow up with a post or PM, and you can always simply ask if all of that has failed (as you have today, and I hopefully helped to get to the bottom of it).
In short: AATW, we agree. In your particular case things didn't go entirely to plan, but this happens very rarely, there's a clear way out of it when it happens, and once I've found a moment to work through that bug it'll probably become a non-event.
EDIT: To give you an idea, this is what the standard message would look like if I were to warn you for this thread's OP:

You have received a warning for breaching rule 1 (no personal attacks). Please try to discuss ideas, rather than the individuals who presented them.
