> It is a common pattern in BEAM pipelines to convert a PCollection<T> to PCollection<String>. It involves the pipeline author having to write a SimpleFunction or DoFn that just calls the 'toString' method on each element and then use it through MapElements or a ParDo. Having a ToString transform would help avoid writing this boilerplate code.
