Consistency really isn't that big an issue, the remarked points are really just details. (Of course in Javascript the use of == really is an issue).
The concept of equals is not as pure as it would like to be but it is not clear what can be done about this, since it is very convenient to have and it is not necessarily the case that there should be a universal concept of equality between all objects (although in practice this is only infrequently an issue in well designed code).
