because a link requires contents.  There's no need for empty a
elements, they add nothing that an author cannot otherwise do.

You've only provided one use case, and it's not a good use case, as
you can just as easily create the a element as have it in the source
in the first place, it's much better to do that.

It's not non-existent though, it's there...

There's no need for an empty SPAN, you don't need any empty elements
at all, there is almost no more code (a createElement and appendChild
instead of a gEBI) and it's much neater, that's certainly not enough
of a difference to make a difference.

No, please stop suggesting href="javascript:   this shows you're
scripting experience is quite limited, the above fails in a number of
browsers simply because the href: will result in a navigation, even if
a null navigation which will unselect the text anyway.   The total
length of the code withotut the a in the source is also shorter, so
this is not a use case.
