Some of us do need/want that aid.  And no,
it's not always obvious what the current order
is.

Indeed; likewise.  And I'm in favor of making
it easy for different people to get different
behavior in this regard.

In general, user customization of the mode-line
is not simple.  When a mode like Dired can offer
useful info in the mode-line, in a few chars, it
should.  And when it can offer users easy ways
to change what's shown there and how, it should.

That doesn't mean that providing a few simple
choices and simple ways to choose will satisfy all
user desires in this department.  Fortunately ;-).
