   Ah, thanks, I wasn't aware of the Archery integration suite. Had a quick glance, and seems to make sense. Was a bit worried it would require support in all languages for shared dicts, but it seems easy to disable languages per folder etc.
   
   One thing I noticed from the JSON format is that it doesn't (appear to) support dictionary restatement, i.e. schema -> dict_batch[id=1] -> batch -> dict_batch[id=1] -> batch -> ... as we have in the streaming format, and that I'm currently explicitly testing in the bespoke tests.
