While I share some of your feelings about IM at work I have learnt it depends on the personalities within the team.
Extroverts and Introverts have different needs. Throw in the needs of Creatives or Agreeable people into the mix and there is a very wide spectrum of different needs.
Assuming all can communicate one way with one tool is a bad idea. Good managers/leaders have some intuitive sense of this.
Especially during crisis. Trait differences and unmet needs get amplified if not handled sensitively.

So whatever heuristics you want to develop on top of your observations - take personalities within your team into account - they all handle stress/info overload differently - https://en.wikipedia.org/wiki/Revised_NEO_Personality_Invent...
