There is "5G" with mmWave and "5G" without mmWave, you've described the latter.

No, actually I described mmave. Just google the words I put in my post and see where it leads you. The problem is that most of the industry, when they think of 5G, just want to send as many 4k streams as possible everywhere.

No I know what those are. But the industry has generally separated a "5G without mmWave" and a "5G with mmWave" as two stages of evolution. Massive MIMO, directional/beamforming, various ML techniques, improved coding, etc. generally fall into the former category

No. 2.4 GHz is in use, as is 5 GHz. Now suddenly 3.4 GHz is a problem?

60GHz is the real new and shiny thing that makes some people worry.

I doubt those will be used much. No range and line of sight is required.

Busy streets, corners, plazas, indoor whatevers, and so on.

Furthermore the end goal is natural convergence with WiFi. The telcos already are pushing Ethernet more and more (backhaul and fronthaul), of course over fibre (because bandwidth requirements, and timing has to be calibrated to microseconds because radio symbols are being encapsulated in Ethernet).

MP-TCP has been recently merged to the kernel, it was already enabled on a lot of phones.

What's missing are ways to allow hosting secure hybrid-cells/APs so telcos are able and willing to offload traffic.
