It can be useful to invoke interpret-trailers for the primary purpose of parsing existing trailers. But in that case, we don't want to apply existing ifMissing or ifExists rules from the config. Let's add a special mode where we avoid applying those rules. Coupled with --only-trailers, this gives us a reasonable parsing tool.
