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 or your local xbps repository the dependencies would differ from the build servers history.
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.
