It's not a requirement, however, if the epub has a TOC and you select one of the entries in there, it's a requirement that it jumps you to the correct place (beginning of the selected chapter).
All readers kind of build an index of the TOC and they load and parse the entire thing to count pages anyway. That's why on most readers opening a book takes several seconds in the first place.
Making a per chapter page count is entirely possible... only requirement is that the chapters themselves are marked.
Readers just don't support it. Personally, I never needed such a feature. I just stop reading or I just finish the chapter, I don't really try to find out where the next chapter is. Don't do that with paper books either as I would more than likely read the chapter title by doing so and this could serve as a spoiler for the remaining part of the chapter I'm currently reading...
