I agree to that.

That are aliases for numerical values, while we're discussing a
keyword alias for another keyword.
I'd argue, that several -webkit- properties were also introduced as
aliases for the standard property names. Also not the same, as they
are names, not values, but anyway.

Applying 'list-item' by default to an element that is not a list item,
does look strange to me as web author. And I am sure there are many
others. So, I believe aliasing may be appropriate in this case.

Tab, you prepared some nice polls previously. Could you create one for
this, so people can decide on it, rather than continuing to argue
here? (Or at least bring it up on your next conf call if you don't
want to include web author feedback.)
