    A flaw that might give people the false impression that `$' after /
    has the same effect as / or ~ after /.

That's a problem, but not a very big one.  This misunderstanding would

read the manual and find out the full facts.

All kinds of incorrect user behavior in Emacs are not equally bad.
But that is not generally true.  Incorrect behavior is not necessarily
a disaster, it is merly more or less undedirable.  One has to try to
judge problems by their importance.
