Even if the changes aren't "meaningful" (which it seems like they are), they still have an impact in how it makes the contributor more comfortable with working on the project. No new contributor is going to start with making massive patches without starting out with some smaller things to get a feel for working with the project.

Agreed, these seem like ideal patches to me for a first contribution. Solves a specific problem, doesn't require a lot of effort on maintainers side to review, and should give them a straightforward path to familiarise themselves with the process.
