What will likely result if vendor-specific headers are used without consideration of their compatibility?

Using vendor-specific headers without considering their compatibility can lead to potential issues with data integrity and flow. When these headers are not properly aligned with expectations of the receiving systems or components, it can result in incompatible data formats or structures. This can cause data to be lost during transmission or processing because the system may not recognize or correctly interpret the data carrying the vendor-specific headers. Consequently, the application's dependency on these headers could disrupt the intended mapping of data, breaking the communication or data handling processes. Thus, the compatibility of headers is crucial to ensure seamless integration and data consistency across different systems.
