It seems people are missing the point: it's not even the submodule incompatibility that's going to become an issue majorly (like python2 --> python3 but worse), the main issue is the loss of traceability for repos that changes in place (which I assume many will do). Imagine what will happen to these:
- SLSA and Provenance or SBOM data in the supply chain security that uses commit hash. All the previous images are now pointing to a non-existing commit
- All the documentation and tooling as the article calls out
- All your traceability links from your project tool to your git repo, they will lose all the past data as it will be dead links
So I hope there IS NOT a migration path for in-place replacement!
