Unifi had this on their old access points (Multi-AP coordination outside of the spec) Now we have 802.11r fast roaming and with 802.11bn (WiFi-8) it will be basically instant, because that standard adds SMD (Seamless Roaming Domain). The APs will talk to each other and share the client connection state.

Yeah, definitely. Fast roaming can work very well, and things like 802.11r and the newer work in Wi-Fi 8 should make handovers even better.

What we’re doing is slightly different though. We’re not only reacting to signal strength or a broken connection. Because we have multiple active paths, we can also move real-time traffic away from a Wi-Fi path that is still connected but has temporarily become bad - for example because that AP is congested or somebody else is consuming a lot of airtime.

So even if the roaming itself is perfect, you can still have a path that is technically connected but no longer able to meet the latency budget.

Another advantage is that this doesn’t depend on the AP infrastructure supporting fast roaming or coordination features. It works above the Wi-Fi layer, and the same mechanism can also combine Wi-Fi with completely different networks such as 5G or Starlink.
