Terrible is a strong word for UX in an area where all products have 95% the same interface, and distancing means changing the appearance of the titlebar slightly...
The keyboard shortcut for opening a private window is Ctrl+Shift+P instead of Ctrl+Shift+N.
As long as the panic Ctrl-Shift-W to close said window still works, we should all be safe.
If we could scrap CTRL+W for closing the tab, it would save my anger on a couple of webgames.
You can't eliminate that anywhere.
Brave lets you change it (or remove altogether). I just did it before posting this to make sure.

I like Ctrl + Shift + P for private mode. Since Ctrl + Shift + N, is inconsistent with ctrl + shift + T, where it open last closed tabs. It should open last closed windows.
For me it is better UX.
So FF just needs to tighten their Tab UI and allow custom keys. Not sure why there isn't a fork of FF that just looks as much as (legally) possible like Chrome.
