Text-only stand-ups also have a tendency to devolve into just posting text into the void than nobody reads, so you may as well move to the even simpler "I need to discuss" flags which reduces communication even more. But then some people don't like that.

I am afraid there's no perfect solution, and it just boils down to people's preferences and the skills of people involved. And the chemistry between them.

I've been in teams which flip flopped over time between "communication worsened" and "wasting everyone's time". Being remote for 15+ years I enjoy the "convivial" side of stand-ups but I hate when they devolve into rote status reports.
