   Pagespeed don´t care about what headers are you using, the only thing that matters is public cacheability. When a resource is optimized, then pagespeed put 1 year for ttl.
   The html himself is served whit cache-control header with max-age=0, so is not stored in any cache.
   The etag:W/"0" is the expected behaviour. The W is a weak validator, resource are semanticaly the same, but not byte by byte. [(doc)](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/ETag)
