If we call the bit not after the recentness of the style but after
what it is about, e.g. "is the section name as a whole (including
its possible subsection part) case insensitive?", then yes, a
two-level name can be treated exactly the same way as the old style
names with a subsection.  Perhaps we should do that rename to save
us from future confusion.

Yeah, I also manually tried when I was playing with the old-style
names to see how well it works.  We would want to make sure this
won't get broken in the future, still.

Thanks.
