That is why trailers are optional -- just drop them for now.  They can
be useful for later responses from the cache, but I agree that it is
tricky to handle them within an intermediary.  It is better to release
an HTTP/1.1 handler now that simply drops trailers than it is to wait
for a more complicated solution.
