Review comment:
       > Is it OK to just skip those recursive fields?
   
   I'm currently breaking recursion by skipping recursive fields at the 2nd 
level. That should be OK for almost all use cases. Here's an 
[example](https://github.com/apache/beam/pull/16947/files#diff-4323038b8a26fb9243b5d19637a1c8c39cfd418dd40f59064d40cab8eb04ae51R79-R124)
 for a model class called `AttributeValue ` that contains a map `m` of 
`AttributeValue`s and a list `l` of AttributeValue`s.

> SqsIO.write should support arbitrary types T and be implemented in terms of a 
> mapper function that converts T into an AWS request.
> The current implementation of write as 
> {{PTransform<PCollection<SendMessageRequest>, PDone>}} is a rather poor 
> choice. It may requires an additional unnecessary serialization & 
> deserialisation round. But even worse, the current 
> {{SendMessageRequestCoder}} does not support any advanced configuration 
> beyond queueUrl and messageBody and will silently drop it without even 
> warning the user.
