Inconsistency with .attr() accessor and mutator for missing attributes

When .attr(attrName) is called on a selection that does not have an attrName attribute, undefined is returned.

When .attr(attrName, undefined) is called on a selection, the attrName attribute is not removed. Instead .attr(attrName, null) must be called to remove the attrName attribute from the selection of elements.

For consistency, I see two options being available:

Option 1

<div data-example="example"></div>
  $('div').attr('data-example', undefined);

should result in:


Option 2


should result in:

.removeAttr should be used to remove attributes. Setting to null or undefined has no affect (by spec) on some attributes.
