If a class only overrides __getattr__, then I agree it should only add to
__dir__ (most likely by using a super call as Georg suggests).
If it overrides __getattribute__, however, then it can actually deliberately
block access to attributes that would otherwise be accessible, so it may make
sense for it to alter the basic result of dir() instead of just adding more
attributes to the end.
Cheers,
Nick.
