> What is our plan to move forward with binary format? I've not plans regarding it. Moving forward with it will happen when someone comes with a metadata change which will break text metadata users (i.e. almost any metadata change).

I can't remember the exact details, but there was a conversation about whether to make each users specify the metadata version in their configuration, or to make a flag in the metadata store that we flip to enable it. I don't think we settled on anything, and it turned into a "Let's decide this when we need it" type of thing. The important thing at the time was to make it so clients can _read_ binary metadata, so that these clients can then read future updates. -Ivan
