Not sure this is an "only at google" thing. In a past life, I ran Engineering for an App/SMS messaging application. We definitely used an IRC channel as well since the nature of our outages would mean messaging channels could be down. It's also why we didn't rely soley on SMS for our on-call alerting.

I think they meant it’s only at Google that Gmail would not be an uncorrelated email etc.

Though I think Microsoft probably has the equivalent problem with Exchange, Teams, etc.
