As part of our ongoing research on Python dependency management, we noticed a potential improvement in your project’s dependency list.

Specifically, the dependency pyrsistent>=0.16.0 was declared in requirements/core.txt, but after analyzing the codebase, we found that it is not imported or used anywhere.

This PR removes it from the dependency file to simplify maintenance and let pip resolve only what is actually needed. Removing unused dependencies helps reduce potential attack surface, avoid unnecessary version pinning, and improve long-term maintainability.

The pip documentation also encourages auditing your top-level requirements and removing unused or transitive ones to simplify the dependency graph and minimize the risk of version conflicts.
