How long does it need to be reviewed?
It is apparently 6000 pages, so you tell me - does it need 6000 pages, or is this just a tactic to get people to say "I'm NOT reading that"
Last year at this time, while I was working on some network protocol documentation, I wrote a spec that described a small subset (9 verbs) of a protocol I worked on several years ago.
The spec took 120 pages to cover just the 9 verbs.
So yeah, I could easily see a complete set of specs taking 6000 pages, especially if they completely cover all the functionality in Office.
