Possible disadvantages of assertpy

Learning Curve
Developers new to the library may encounter a learning curve due to the distinct approach of using fluent and chainable assertions as opposed to traditional methods.
Limited by Python Version
The library may have limitations in terms of compatibility with older versions of Python, requiring users to ensure their environment is up-to-date.
Performance Overhead
The additional abstraction layer introduced by a fluent interface might introduce some performance overhead, especially in performance-critical or resource-constrained environments.
Less Community Support
Compared to more established testing libraries, Assertpy might have less community support and fewer resources available for resolving issues or getting help.
Dependency Management
Using a third-party library introduces additional dependencies to manage, which could complicate project maintenance and compatibility.
