It's a compromise. You can still get a T480, which does all the things you list afaik. But I'm glad that I can also get an X1 Carbon, which is much thinner and lighter. These things aren't achievable without making some compromises. And for how integrated they are, they're still incredibly repairable. Here's the hardware maintenance manual for mine (X1 Carbon 5, last year's model): https://download.lenovo.com/pccbbs/mobiles_pdf/x1_carbon_5th.... It includes instructions how to replace virtually every part in the machine. Broken screen? Fried mainboard? Broken TrackPoint? This is how you replace it.

The more annoying change (imho) is how hard it's become to replace the keyboard. That used to be really easy, remove a handful of screws, slide out the keyboard, and unplug the connector. Now it requires disassembling the entire machine, at least for the X series.
