We should pay attention to super vicious dependencies.
For example ConfigurationOfPhexample dependent on a new version of StateSpecs.


baseline21: spec
<version: '2.1-baseline'>

spec for: #'common' do: [
spec blessing: #'baseline'.
spec repository: 'http://www.smalltalkhub.com/mc/Phexample/Phexample/main'.
spec baseline: 'StateSpecs' with: [
 spec repository: 'github://dionisiydk/StateSpecs:v2.4.x’].
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

spec package: 'Phexample' ].

Since this baseline is referring to github, it means that old users of Phexample
cannot load anymore their code. This is funny because they cannot load their code to 
be able to fix it to load in recent pharo version. 

So Alain cannot migrate his project because petitparser use Phexample.
