However, Slack doesn't allow you to a) stay alertable to a subset of the company (e.g. people you are working heads down with on a project) while b) ignoring everyone else in the company. Even if you stick those people in a common channel and mute the rest of the channels you are in, people can still jeopardize your focus with a single at-mention or DM. Just anyone can hijack your sidebar.

Slack doesn't respect something as simple and fundamental as the focus of a small team within a larger org. But if they did that, they wouldn't sell as many subscriptions, because it would be less addictive, I guess?

This isn’t a slack thing, it’s a humans thing. Whether it’s a telephone, a marked urgent email, am @mention, or whatever. If someone wants to get your attention, that’s not a technology problem.
