I currently have that setup for my old work-provided Macbook Pro from 2017. One cable going from the laptop into the thunderbolt dock (no extra cables, as the same cable also charges the laptop). The dock outputs to 2 external displays, one 4k@60hz, another 1080p@60hz. Same 2 monitors are also plugged into my Windows desktop directly. Been using that setup for almost 2 years, zero issues whatsoever, so I have no idea what you are talking about. I would be willing to concede that I just got lucky with the stability of my setup, but my friends who use similar multi-monitor setups with thunderbolt docks have no such issues either.
