Versions 8 and 9 support response trailer headers for HTTP/2 and HTTP/3 and lack this for HTTP/1.1 with chunked transfer encoding.

Need it for implementation of OData-Error trailer header as described https://docs.oasis-open.org/odata/odata/v4.01/odata-v4.01-part1-protocol.html#sec_HeaderODataError

Describe the solution you'd like
