> Is there a good argument for actually using Rust for such things?

Can't speak for the author, but I'd choose Rust over Go/Java/Python for such projects for following reason:

* Rust is a more pleasant language to work with, i.e. Sum type, pattern matching, and Drop trait closing resources/cancelling tasks.

* Type system is much more robust than Go and Java, resulting in better quality code with less requirement of unit tests.

* I don't care about performance much (for personal projects), but a free performance is always a win.
