The buffer parameter (I believe it is) also does not always apply.

The original open builtin was a thin wrapper around old C's stdio.open. 
Open no longer has that constraint. After more discussion here, someone 
could open a tracker issue with a specific proposal. Keep in mind that 
'mode' is already a parameter name for the mode of opening, as opposed 
to the permission mode for subsequent users.
