That's why I'm asking.
I think the summary is right. What's there is a very late addition. We had a CVE where we originally folded trailers into request headers (r->headers_in), which meant headers changed depending on which modules looked / when you looked. There is a relatively recent PR with someone asking about being able to pass trailers to origin servers w/ mod_proxy for example.
