Well, they're discrete problems. Version control of source code, packaged applications, container images, databases are all quite different. Git is a distributed file manager that operates on files where every change is a commit, and a commit is a set of operations on files, and/or a change to a block of text strings terminated by newlines. Versions are merkle trees of commits. RPM/Deb/etc is a semi-centralized file manager that operates on files assuming each change is a collection of files with executable stages before and after copying/linking/unlinking. Versions are arbitrary key=value pairs which optionally depend on other versions, with extra logic to resolve relative versions. Docker/OCI is a distributed file manager that operates on layers assuming every layer is a collection of files overlaid on other layers, with extra logic to do extra things with the layers at runtime. Versions are (I think?) merkle trees of layers. The database is going to need a helluva lot of custom heuristics and operations to do version-control, because how you use it is so much different than the above. Databases are much more complex beasts, require higher performance, higher reliability, tons more functionality.
