"MergeTrailers on" will not put the client's trailers into the ones to be sent to the backend (as you may expect), but instead it merges them into client's headers (obviously after those have already been sent to the backend...). This directive aims to preserve the previous behaviour of httpd (which was wrong, but we wanted anyone broken by the change to be able to recover). The new default is to discard the trailers (or more exactly to put them separately in the request/response trailers table, but nothing is using it for now). I think you should request an enhancement on the bugzilla for mod_proxy (at least) to handle/forward the trailers, that's not the case currently, and I agree this is the sequel. Please note that the trailers shall not be handled/forwarded blindly, the RFC 7230 (sections 4.1.2, 4.3 and 4.4) is quite strict about acceptable trailers and how they ought to be announced in the headers (TE, Trailer, ...), so clients have to conform too.
