       Do we still need a TODO?

> As discussed in BEAM-673 runners can allocate workers to accomplish their 
> work in a better way if they can take into account some hints from the 
> transforms, e.g. a source can hint data locality and with this information 
> the runner can allocate the workers in an better way, this can also be the 
> case with a particular transform that can suggest to the runner to be 
> executed in a worker with a specific resource, e.g. GPU.
