order to avoid discrepancies, you cannot edit a strategy object manually.  
The strategy to delete revisions is the following:  
- the `snapshot` folder containing the revision symlinks is deleted.
- blobs files that are targeted only by revisions to be deleted are deleted as well.
- if a revision is linked to 1 or more `refs`, references are deleted.
- if all revisions from a repo are deleted, the entire cached repository is deleted.
