In two of your cases this operator is pretty shit because at some point you’ll probably want to offset the access (this isn’t a knock at you but at the feature).
This operator would only really be relevant to the last case which rarely comes up outside of infrastructure/library work (building a tool building tool) and usually those code bases are cautious to adopt new features too quickly anyways for portability.
I’ve done serious C++ work (not much in the past decade though) - while references are absolutely amazing and you essentially want to pass by const ref by default I think well written maintainable C++ should maybe have a dozen heap objects tops. C++ is a better language if you generally forget that pointers and bare arrays exist.
Just again - I think you’re right and the fact that your list is only three things long (and arguably two of them would be misuses) is a pretty clear sign that this is an incredibly niche feature.
Why do you even have pointers to pointers?
Pointers just point to memory addresses, and because pointers are stored in memory addresses, it just kind of naturally falls out that way.
Because pointers are real.
many reasons, for example

I don’t think this operator is a real feature, tbh 😅
