Comment:

 We have not yet addressed the case where clients _need_ C-L as for Range
 requests

 Replying to [comment:4 slink]:
 > * On `Range` - from #1500:
 >   * trust C-L whenever we know it
 >   * add `std.wait_body` for use in `vcl_response` to prefer to wait
 until we know a C-L for the cases where we don't have one before reading
 the response (read: response sent chunked)
