It would be expensive and mouse cursors are not the most enjoyable with these things. You really have to crank the speed to use a mouse cursor without extreme frustration on eInk and that comes with a huge quality loss. I imagine most people need color for certain tasks even if it's not accurate like making a PowerPoint or something. For most people I think it would be more of a frustration than a help when running Windows.
Boox and others like Boyue do make Android eInk tablets which are pretty flexible. You don't need a mouse either which solves that problem. Very good for reading PDFs. Termux and a good text editor like Emacs or Vim can let you get some work done.
Touchscreen and keyboard commands. I use those systems this way and efficacy is high.

You must mean, "use the A2 mode". Not really, on the contrary: on GU (Grayscale Update) they mouse cursor will leave a trail that can be more helpful than an annoyance.
Yeah, I retried it directly connecting a mouse to my Note Air and it's better than I remember. I think before I tried a screen sharing app with it connected to a PC and maybe that's why I thought it was so bad.
