This probably isn't the answer you're looking for, but vpr being memory-safe isn't a benefit that it has over rm, since rm apparently doesn't allocate any memory (as @radiant_bloom@lemm.ee wrote).

the first thing you mentioned as a benefit was memory safety.

Looks like I worded my project description poorly. As I wrote in another comment, I meant that this alternative is memory-safe (being written in safe Rust), but not that rm isn't.

edit: I've updated the post's title to clear things up
