If an object is being used by a different application, is it acceptable to modify it for your own application?

Modifying an object that is being used by a different application is typically not acceptable due to potential issues that could arise, such as data integrity, functionality disruption, and unintended consequences for the other application that relies on that object. When an object is shared across applications, any changes made could affect how those applications operate, leading to bugs or loss of crucial functionality.

The concept of maintaining strict boundaries and control over shared resources is essential in software development to ensure that all applications continue to function as intended. Any modifications should be coordinated and agreed upon with stakeholders or teams that depend on the same object to preserve the stability and integrity of the applications involved.

Thus, altering a shared object without proper coordination is generally not advisable and is often explicitly restricted.
