Agreed about being able to access some backlog being important, but even in well-implemented systems with good search etc. I personally haven't found backlog older than maybe a few weeks that useful.

Similarly, I'd disagree about friction, but I can see how that might be cultural/personal preference - none of the chat systems I've used provides good-enough tracking of "I still need to take care of this" compared to email clients with a few flags.
