What is the primary benefit of using domain-separated Application Properties after the Paris upgrade?

The primary benefit of using domain-separated Application Properties after the Paris upgrade is improved customization for different domains. Domain separation allows organizations to tailor their applications and data configurations to meet the specific needs of different divisions or user groups within the organization. This is particularly valuable in environments where multiple business units operate with distinct processes, terminologies, and data requirements. By leveraging domain-separated properties, administrators can ensure that each domain has access to tailored configurations and settings that reflect their unique needs without impacting other domains. This flexibility enhances user experience and operational efficiency across the organization.

The other options, while relevant to system optimizations, do not capture the essence of what domain separation primarily achieves. While it may lead to better performance or a cleaner data structure implicitly, the standout feature is indeed the ability to customize applications more effectively for individual domains.
