[issue41523] functools.cached_property does not satisfy the property check

[Raymond Hettinger]

I recommend closing this.

As Serhiy pointed out, they are profoundly different.  Currently, a user can rely on the isinstance() check to differentiate them.  So, changing the behavior would be a regression.

AFAICT, a user would not be able to deduce anything useful from the isinstance() check returning True in all three cases.  Essentially, all they have in common is the concept of caching; otherwise, the mechanisms and implications are entirely unrelated.
