For a project with lots of modules, and you want the same dependency across them all, I think version catalogs are helpful.

When a dependency is only used in one place, I think version catalogs are an unnecessary layer of indirection.

Spotless does not have a large number of modules, and most dependencies are only used in one place, so I don't think a version catalog will make things easier.

I'm still open to this though. What am I missing?

This is mostly useful for #2705.

• this is a good idea, and the reason was patiently explained to me here: Use gradle-buildconfig-plugin to generate dependency versions #2705 (comment)
