Forgive me, I didn’t watch the videos: is that what the Dream Router supports - normal wired WAN uplink, plus 5G failover? If so, yes, that’s very attractive.
I have a T-Mobile backup home internet plan, and when I had a rack set up, it was my failover from fiber. The Dream Machine Pro did auto failover and failback flawlessly. However, I recently moved, and am redoing my homelab so I have no rack right now; internet is from a Dream Router, so I don’t have auto-failover. I doubt I’d buy this for the small window of time I expect to be in this situation, but if you didn’t have or want a rack, an AIO with failover would be great.
Yep, that's one of the main reasons people are excited for this. Instead of a dedicated ISP modem with 5G, you can just use this, plug it into a gateway WAN port set up as the secondary failover connection, and you'll have a backup if you get knocked offline.

The 5G unit itself also has its own failover with support for two 5G SIMs.
"All are equipped with dual SIM slots, with one SIM replaceable by eSIM, and are fully unlocked: any major carrier, any type of deployment, with one piece of hardware."
