Note this is different from `Vary: Accept-Encoding`,
which is important for compression (e.g. gzip), and usually added by

* No longer sets `Last-Modified` date in HTTP response headers in `DataObject::__construct()`.
Uses `ETag` calculation based on response body which is more accurate,
and resilient against partial and object caching which can produce stale `Last-Modified` values.
* DataObject no longer automatically invokes `HTTP::register_modification_date`
with LastModified on construction. User code should instead invoke
`HTTPCacheControlMiddleware::singleton()->registerModificationDate()` explicitly.
