Very cool, much more interesting than the old fatty Gundam. It was totally lame that the Throne had the same trick.
We don't know what material those swords are made of. For all we know, Ali's could even be lighter if it's mostly made of less dense material. Also, if you think of the fighters or tanks or APCs of today, it's not like there are huge fundamental differences as such between them, so why should there be between mobile suits? They are all made for the same purpose, except those purely underwater ones, which were, then, quite different. Moreover, being human shaped it makes sense they would be able to kick and it doesn't take anymore a genius designer then to place some extra effect in for those kicks. Shoes with (poisonous) blades are old fare in stories.
