I disagree: technically, it can be made to work, at least with some effort.

On my Lenovo X1 fold, I do get 0.5%/h of sleep, cf the slope of the sleepstudy curve on Windows https://csdvrx.github.io/X1_Fold_(20RL_20RK)_Optimization/pa... ; the root cause of most of my problems were the Intel drivers, more details on https://csdvrx.github.io/

Just turning off wireless with a powershell script before sleep helps a lot, on Linux of course you have more leeway with systemd-suspend hooks.

We've got very similar experiences with Dell
