Electric cars produce far less brake dust pollution than combustion-engine cars

No reason for it not to work, even more so if you think to downshift. It’s more common with manual as downshifting is a lot more natural but not fundamentally different.

It’s just trivially easy with electric thanks to regen braking.

Though with modern cars getting heavier if you have a small ICE these days you have almost no engine brake which makes some cases more difficult (unless it’s a mild hybrid with an electric kers like some of the small engined fords). SUVs tend to have giant engines and pretty high rolling resistance, which I’d think would somewhat compensated for their higher inertia.

It’s all about learning your car’s behaviour and planning for it.

I don't know about today's engines, but some early fuel injected engines would actually use more fuel when engine braking. In those early designs spark could not be cut off, so if this extra fuel were not added then the mixture would run very hot and risk pre-ignition and damage. I don't know about carbureted vehicles.

It only applies to mechanical injection and carburettor engines. With electronic injection, which is the norm since the 80s, this is not a problem.
