Oh, we use it all the time. It’s just that many people habitually
write Е in place of Ё.

And this is exactly the reason why char folding becomes relevant for
this particular pair. When searching in a text by someone other, I
will want to fold so that I find occurrences where I would write Ё but
other would replace it with Е. Likewise, those other people, when
reading my text, will want to fold in order to find occurrences where
they would write Е but I would write Ё.

In this situation, you will want to not fold, so that you can search
for all instances of Ё and decide which to replace with Е. (Even when
the policy is to avoid Ё, it is still mandatory in cases of
ambiguity.)
