I never really used Arrows, let alone stream transformers with an Arrow interface, but yes that makes sense. With the conduit library you’d use ZipConduit which has the same characteristics.
On reddit, in reply to the first blog post, someone asked how ZipConduit compared to our parallel streams. Maybe that’s helpful for hosh as well.
