Why Are Jujutsu's ID Prefixes So Short?
(jonathan-frere.com)
Jujutsu is a relatively new version control system that is designed around working directly with commit-like objects called “changes”1. Each change has an ID, and these IDs are important because they’re the main way of referring to different changes2. To make referencing these IDs a bit easier, Jujutsu often shows ID prefixes rather than the whole ID when displaying commits (such as in the jj log command).
