If I'm installing build deps over a slow network connection, I'd like to see the output. It would be awesome if this transformation could be applied to any arbitrary Property. I don't immediately know how to do that, although it seems useful that all process spawning already goes through concurrent-output, which can buffer the output and display it only when the command finishes. Perhaps an extension to concurrent-ouput could let it buffer the output of all commands run by a property and then discard the buffer if the property finished with NoChange. But I don't see a way to make this work when multiple properties are being run concurrently. """]]
