However, a more important question is whether there is an actual problem to
solve.  I see that ap_http_header_filter() features a whitelist of headers
that are sent for 304 responses (http_filters.c:1428), and all headers such
as Content-Encoding are filtered anyway.

AIUI Transfer-* headers should be filtered. Content-* headers must match
the specific ETag as if the response was 200, from my reading.
