While we have strict rules for some languages, it's very helpful to
count for errors which natives and non-natives may make and fold as much
as possible - if folded search gives too many false positive that may
just be an indication that a more specific (not folded) search should be
used.

I now realize that I'd like to see folded even distinct letters like
Russian Е and Ё - I cannot tell in advance when the author did it
correct.

However, having folding on by default will certainly tell me that Emacs
is not respecting Russian alphabet, which some people here wrote about
too.
