What is a primary reason for using a different domains table in certain scenarios?

Using a different domains table in certain scenarios primarily helps accommodate customers on older releases without the Managed Service Provider (MSP) plugin. The MSP plugin introduces enhancements and functionalities that may not be present in older versions of software or systems. By utilizing a separate domains table, organizations can ensure compatibility and provide support for these legacy systems, allowing them to function effectively even without the latest updates or features.

This approach ensures that customers who have not yet updated to the latest version can still access necessary functionalities without experiencing disruptions or limitations. The design of systems to cater to both legacy setups and those that are newer is crucial in service-oriented environments, where customer diversity in software versions is common.
