Dependencies

[David Carlisle]

Sorry about that, splitting up the oberdiek  bundle has a chance of
having that effect on people making minimal texlive installations (it
broke some of the overnight latex3 tests on travis CI for the same
reason until we adjusted the packages installed)
but having 95 packages in one bundle and taking an hour just to
rebuild the pdfs to make a ctan upload every time you touch any of
them was making the collection painful to maintain.
(the time could be reduced using a faster machine or more parallelism
or other strategies, but the administrative complexity of maintaining
the whole thing as one interlinked bundle would remain)
