Get it as smooth as possible. Then skim it 2 or 3 times with powdered joint compound like easy sand 90 if you want it smooth. You could do a rough plaster look also. Check out YouTube videos for that.

I am seeing conflicting suggestions about using drywall compound on top of thinset. Is it really acceptable?

I agree, but for "Get it as smooth as possible." I'd only knock down any bumps sticking out of the current thinset wall. Drywall mud will stick to it, and it will stick better to a rougher surface.
