Thierry, If I'm not mistaken, Esteban is referring to the fact that in FileTree we are still using Monticello to do the load of the packages and even when we are running metadataless, we end creating fake meta data to simulate an mcz ... you and I have had conversations about ways to eliminate this "requirement" because it is meaningless in a git context ...

Yes, this I understood. I do believe that what I suggested at one point (have the ability to compare versions with an 'isAncestorOf') would be very nice for that transition (work in mcz as well as on git with/without metadata).

I would like to listen to your ideas about this topic, but I am not sure it is possible to achieve that compatibility. In fact we tried to do it for Iceberg and at some point we decided to abort it.

On one side, trying to re-create monticello sequential file numbers in git is simply not possible, at least in a reliable way. On the other side, loading the graph of package versions and dependencies is really slow for big repositories (such as pharo-core), once we removed that requirement Iceberg got like 100x faster.
