It's still an isolation machine even with the display. It's designed in a way to make it so you can experience all your content with no interruptions. It is arguably THE most isolating product Apple has ever made.
The hell is "you people" supposed to mean? I have been following the development of VR (oh I'm sorry, "spatial computing") ever since the Oculus DK1 and have used HMDs since the OG Vive. I know more about the XR industry than the majority of people in this hellhole of a forum who most of which have never even touched an HMD.
Again: That is a function the display fails at and for most, it is completely useless. Where would I mostly use this thing? At home, alone, with no one to see my eyes. Not only that, but what if I don't want people to see my eyes? Then the display is just wasted space.
And again, you can get the same effect of the EyeSight display by just gluing googly eyes to the headset, a point literally every XR expert has pointed out.
Cutting the Eyesight display would not only simplify manufacturing thus lowering costs, but it also makes it easier to open the headset to fix something, as well as reduce weight
Acknowledging that none of us have used or interacted with the AVP or anyone wearing the AVP, I'll share that with both my Vive and DJI goggles for their FPV drone, the question of seeing out from the headset and people around you having some cues as to your status have been a huge issue.
Less with the Vive, but HUGE with the DJI set where the primary use case is outdoors in not-fully-controlled locations, and where a second person present is essentially required, both by law (in the US) as a visual spotter, and functionally since the pilot is doing a mission-critical task in the headset and unable to respond effectively to people, animals, vehicles or other environmental hazards.
As you suggest, all VR/AR goggles are inherently isolating, we're starting so see attempts to solve this for both inbound vision, and outbound cueing for people around the wearer.
Apple's Eyesight solution is an interesting approach, by far the most aggressive attempt to manage the outbound cues we've seen. It remains to be seen whether it's an interesting starting point in the field, becomes the new baseline, or is simply an expensive disaster that no-one ever has to do again.
You note that your personal use case is alone at home, and for that the Eyesight isn't helpful. However, that's not the only use case, especially in enterprise settings where someone might be in the headset for AR use with other people around, or on an airplane, or anyplace with others around.
Strong cues about how and whether you can interact with the wearer seem not just valuable, but critical. Is there any answer that actually works? TBD. Is Eyesight a good attempt? TBD. You may well turn out to be correct about the Eyesight approach, but I'd argue pretty strongly that effective outbound cueing is going to be a significant part of any eventual rise of goggles
