Even if they didn't just patch the game, this whole argument falls flat. If you were that bent out of shape about developers initial intentions you'd just fix the game to 30fps as it was originally intended and bam, away you go, historically accurate Vanquish.
I think most people are giving the existence of bugs a pass because they fairly assume the game is probably being ported for minimal budget on a skeleton crew. If they weren't at all responsive to community feedback in this or Bayonetta's port there'd be more justification for melodrama.
