Constraints of NGINX location block

Checks only request_url value.

This is bad if URL does not match the file path and you need a check by request_uri. See the use case here.

Ignores query part of the URL like ?lang=

Forbids you to use more precise location blocks like /results?v=1. Sure You can use if block inside it but it has it’s own drawbacks.
