The last time I looked at this issue, in the context of an optimizing
load balancer where we would have loved to set ETag in the trailers, I
found that browser support was almost nonexistent. Things haven't
improved much since then:

If there's widespread interest in trailer support, HTTP/2.0 seems like
a great opportunity to make it mandatory.
