I quite agree here, I remember Xan complained about the cyclomatic
complexity of the notebook [1] between others, which means it's insanely
hard to get anything done on the notebook layout/rendering that covers
all possible cases.

Other sources for this complexity are ltr/rtl and scrollable tabs, of
course we can't get rid of that but IMHO tab-pack is quite senseless and
deprecating it will help removing a lot of cruft in the future.
