   > @gianm I made a thing that if you paste in a firehose based input spec into the data loader it will be magically converted to an input source based one. I need that because the data loader will soon _only_ work with input sources. Do you think this is a bad idea?

   I was imagining people would convert them by hand, based on the new docs.
   
   The conversion isn't always possible, since there is stuff that firehoses can do right now that input sources can't. I think the data loader doing it for people would be really helpful if feasible, but doing it 'blindly' won't always work for that reason.
   
   Btw I think it makes sense for the release notes to say not to use input sources and formats until you're pretty sure you won't want to roll back. Since using them will mean that you can't do a rolling downgrade anymore.
