Try editing paragraphs in InDesign. In practice, it’s really not much of an issue, because paragraphs don’t actually jump around all that much, and to the extent that they do, it’s really not particularly distracting.
I tried it in Photoshop which since CS2 (or so) has an implementation of the Knuth & Plass algorithm. I found it quite distracting myself. Granted, I was on the lookout for text jumping around and had hyphenation disabled.
