Like not moving the surround speakers forward when adding surround back speakers, and then not hearing the level of difference others have been describing.

No dubbing stages and no movie theaters have surrounds at ear level. Why should I?
To get greater above-vs-around separation than a commercial systme, IF you fancy that.

According to Brian Vessa, Executive Director, Digital Audio Mastering, Sony Pictures Entertainment, and Chair of SMPTE 25CSS (where all the work on immersive cinema standards is happening), the definition of mixer's intent is what the mixer heard when he mixed the soundtrack. This may seem so obvious that it should go unsaid.
The mixer can only mix within the constraints of the reproduction system (dubbing stage). That's why I've said "director's intent". It's not the same.

BTW, I heard very nice overhead effects at the Arclight cinema, before they installed Atmos. It's clearly better, in cinemas and my home, with the Atmos speakers.
No disagreement about angles. But if the surrounds are above the listener's head, I'd expect him to hear sounds coming from above. Indeed, when we didn’t have speakers physically above, having the surrounds somewhat higher than head height was the only way to extend the 'bubble' vertically. But now we don't need to do that because we have actual speakers above us to handle any content that needs to come from above. Now we can have the sounds 'around' us coming from around us (with lowered surrounds) and sounds above us coming from above us.

Yes, I fully agree with that - in my case, the HT is movies only (makes life so much simpler). If I listened to a lot of non-movie content, I'd also want to optimise for that as much as possible. And if most of my listening was music then I’d definitely optimise for that of course.

Well, at least in the case of the 5.1 vs, 7.1, the two conditions are both justified by actual practice. In the case of lowering surrounds for Atmos, there is no precedent, just the expediency to improve the apparent benefit of the new features (height speakers and upmixing).
