Good point... although doesn't the page optimization feed back into paragraph layout? >> - Most large works are divisible into chunks separated by page breaks >> and possibly page breaks that force a "recto".

They have a lot of potential. Sounds useful. It's impressive if you can get "a correct table of contents in the first run" (says http://www.gust.org.pl/BachoTeX/2008/presentations/ms/handout.pdf) >> page number of each page reference.

IIRC, Knuth even says in the TeXbook that a really pathological case might never stabilize.
