 Review comment:
   So the v1beta3 protos expose neither the windowing strategy nor a reference 
that can be used to tie back to the original PCollection? Unfortunate...
   
   In this case, let's add a (possibly memoized) method 
`getWindowingStrategyForCoder(Coder<?> windowCoder, componentsBuilder)` rather 
than creating and injecting a default and then later possibly overwriting it. 
It can have a case for Global and Interval windows, and throw an error 
otherwise.
