Audio line in and out are combined into one and moved to the side of the iMac. The four USB ports are still there, they are now USB-C and USB 3. Firewire technology is incorporated into Thunderbolt and Thunderbolt 4 now also uses USB-C connectors. The Ethernet port moved to the power brick. All the connectivity is still there, it's just much faster and easier to plug-in. 💁
OK again, you seem to be missing the point. I am not suggesting we need firewire, etc... simply pointing out the abundance of useful ports as a built-in, direct-connect hub in the past. Conceptually now a single Thunderbolt port is enough because then one can buy a hub or several hubs to daisy chain to get all ports they need.
No need for ethernet- just get a hub with ethernet on it.
No need for combined audio in/out- just get a hub with that port too.
In the past though, iMacs offered the "hub" in the all-in-one price. Now we march towards a time when up to all such ports except maybe one could be jettisoned out to a separately-purchased hub.
And again, you make an argument for wanting it "all in one" for aesthetics which is then undermined if adding a hub is needed to convert combined-in-one-type-of-port to port types to which external stuff can actually connect.
Is this "hub" better than former hubs with many more ports...
If one has only a few things to connect and they are USB-C and/or Thunderbolt, then maybe the answer is yes. But as soon as you need to connect something NOT USB-C/Thunderbolt, something will need to be appended to the "all" in one... which is often a hub, which then tends to be a permanent addition to a desk.
Even if one wants to make an argument about "the future" USB-C/Thunderbolt, then how about 7 or 8 such ports in the back instead of only the 4... like former iMacs had more than only 4? In my experience, 4 is NOT enough: one will need more ports very quickly and thus a hub of some sort will soon be on that desk too.
