I don't read literary criticism much, so I can't make any response that would be of interest to your readers. But I should say that I went to a fascinating lecture by Geoffrey Hartman a couple of years ago, in which he closely examined a passage from Wordsworth's Prelude and in passing quoted (relevantly and understandingly) from Robert Duncan's poetry. Perhaps Hartman is not among the critics you are thinking about, but if he is, then few of your strictures could be applied to that illuminating lecture.
