It records the first version a shared library was introduced to create dependencies like `librarypkg>=firstversion`.
Automating it by using repository metadata would introduce state that depends on the build history so its not reproducible anymore and depending on the history xbps-src would generate different dependencies.
Automatically changing tracked files when running xbps-src is also not that nice and would probably lead to more issues than changing the file manually if required.
