I'd be happy if they'd kept the Magsafe and two USB3 ports and the SD-Card reader. Add 2-4 USB-C ports on top of that and I'd be happy.
Using a USB-C adapter for Video output seems acceptable to me since VGA ain't coming back and there are quite a range of replacement connectors which are all semi-incompatible to each other. An adapter for wired Ethernet is also acceptable since you're connecting to other wires anyways. Not optimal but acceptable.
Not acceptable, though, is having to carry an adapter to connect a common USB-Stick or SD-Card. These things won't go away in the next 4 years.
