I agree that would work, but culturally that's not how most organisations seem to be using it. Instead Slack seems to be viewed as a synchronous messaging tool - "if I send you a Slack msg, and I don't get a response within 2-3 minutes, something is wrong"
I work for several different organisations that use Slack. Every time I start working at one, I turn off notifications and mark myself as busy or away, then jump onto Slack at logical intervals during the day to respond. Within a day or so, I have people asking if I'm OK, then when I explain, I get told that there's an expectation that "people should be always accessible via Slack" (generally a mealy-mouthed version of that, but the message is clear).
To me, Slack is like sitting in the desk next to the only coffee machine in a large office - constant interruptions and zero chance to get into a flow state.
