Also the question "how many pages is long this ebook?" would be impossible to be replied precisely.

... you could answer the question: how many screens remain? ... which is precisely what some people want to know. And, unless you change font and margin settings significantly per book, the number of screens should give you a pretty good idea about how long a book is.
Displaying the number of screens would also be similar to the common practice of (non scientific) printed books where editions/versions are typically not identical regarding page counts.
And for some people the cognitive dissonance between page (screen) turns and displayed page numbers is somewhat disturbing/annoying.

The actual ADE standard as used by KOBO is not as informative/stable as it seems at first glance as a reference since it is referring to the number of bytes in the compressed epub source file rather than to a count of displayed characters. Thus reformatting an epub might change this page count to some degree and the 'fixed' reference is only fixed with regards to one (unaltered) version of an epub. How many characters you will actually see on a displayed 'page' actually depends significantly on the formatting style implemented when the epub was created.
