I am aware of the potential harm of giving Metaknight a safe ground approach, but never the less, the metagame needs SOME sort of offense boost, as well as something to increase the skill gap for when MLG comes up. Without a way to cancel dash into anything, a lot of characters are left without an approach, and matches are left waiting for someone to approach. Yes, this gives Metaknight more incentive to hang off stage, but it also will encourage others in other situations to approach as well as giving them the tools to do so.
