Most real world HDR productions target 1000 to 1500 NITS for the final output, which is around 9 to 10 stops.

It doesn't mean anything to say 1000 Nits "is 10 stops". Stops are relative. 1000 Nits is about 10 stops more than 1 Nit, but 1 Nit has no special significance. SDR displays go much darker than that, and HDR ones more so. Also screen contrast ratios and scene contrast ratios are not the same thing.

But I agree with your point that pushing the exposure too far one way or the other, to protect either highlights or shadows can be a bad idea.
