I assume this feature is on the roadmap ? Brian and I have been talking
about it and I think this is a crucial feature. I suggest we add this
before GA. Thoughts ?
I just commented in detail on another post. Whether I think it's crucial
depends on the details. Is there any other factor you're thinking of
