I understand that, but there's also no guarantee the game would be out in a timely manner and that it'd work as it should. Given how little light cares about the whole KS nothing would surprise me,
If they made just one mistake it'd be alright, but they made several and they're aware but they still refuse to fix them; launching the KS during the holidays, hiring incompetent PR, not looking into how kickstarters actually work, lack of communication, crappy rewards, not taking any advice from their Prefundia and actually changing things for the worse etc. They're also either straight out BSing with the whole Vita stretch goal or they just put the goal there to milk money from the vita fanbase. At this point, I don't think we'd get the vita port even if the KS magically reached the stretch goal. They just don't care.
