I have (121 pages, BTW), and it shows that things are going
to get worse.  (If you've ever heard me rant about TIFF
before, imagine I just did it again. :-) )

To get around complexity, they've defined a subset
(Baseline TIFF) for lazy people to implement.  (I didn't
say "sane" because sane people don't encourage use of
TIFF.)  Beats the multiple subsets in TIFF 5, but it shows
they know they have a problem, but not that they plan to fix
it.

The new spec (should I put it on sonata/nova?) says that
"Baseline TIFF" grayscale images should only be 4 or 8
bits.  #@*! that!  How could they leave 2 off that list?  What
the Hell were they thinking?
