Agreed. As someone who often advocates for the use of Rust to speed up perf-sensitive Python functions (and in particular, in the GIS domain), this sounds like they haven't fully understood the problem or thought about how to solve it more efficiently with a spatial index (which is easily done in Geopandas, let alone PostGIS). However, the post is a bit vague on details so who really knows.
