It may be meant for software developers but has legitimate value in other domains. For example, DigitalOcean has their legal team use it as a way of providing diffs on their terms of service and other policies. This type of use case is where it benefits everyone, in my opinion, to reduce the friction to get started.

There are plenty of text file versioning use cases I think, from configuration files for system administrators to LaTeX papers for science students who could benefit and should have an easy path to using it.
