Your 4k and larger displays and USB3.2gen2 hubs can still happily get power from a 93 year old 110V outlet.
They won't work off a Lightning port, though - it physically doesn't have enough wires (it only kinda-sorta supports USB 3.0 on some iPads with a propretary dongle). That's increasingly an issue with iPads and high-end iPhones being sold as "serious" photographic and video production tools, and once you start going USB-C with iDevices it doesn't make sense to have two different connectors.
Apple would have needed to launch "Lightning 2" by now, which would be pointless when USB-C exists and was being rolled out to Macs (when Lightning launched it was better than those horrible microUSB connectors). On this one, the EU just threw Apple into the briar patch and gave them someone to blame for having to buy a new clock radio stand.
Having USB-A ports is handy, esp. on a Studio where there is plenty of space - but on a desktop, using adapters isn't the end of the world provided you still have the same number of holes to stick them in to. What has tended to happen with other Macs is that USB-A, Ethernet, HDMI etc. just vanish leaving you reliant on hubs/docks to "break out" the various features of a small number of TB ports.
