Of course there are things that are done differently today. But those things have nothing to do with the definition of chareidi. That’s why even today there are many Jews who do things very differently from each other but can all still be considered Chareidi (such as Sephardim and Chassidim). According to the definition of Chareidi that both Joseph and I were using, most Jews from the time of Har Sinai until relatively recently would be considered Chareidi, despite their differences, because those differences have nothing to do with the definition of Chareidi.
If you define “Chareidi” as “Religious Jews excluding Zionists”, then why would you even ask the question?
By your definition (which I reject), any Orthodox member of Meretz is now “Chareidi” because they aren’t Zionist?
So sure, everyone is now Chareidi, so the word has no meaning.
