Case folding can make a lot of sense in some contexts, yes.

By "plain text" I'm guessing that you might really mean text
written in a natural language (sentences & such)?  In that
case (!), I think you are right.

And that is the behavior we provide, to start with, for Info,
for instance, regardless of a user's customized value of
`case-fold-search'.  And that's TRT.

Maybe that is the main use case (!) we should consider, for
the general default behavior.  Dunno.  Still, the simplicity
of literal search (no guesswork) argues in its favor.
