I’m working on a Java web application and noticed that we have both a plain.war and a standard .war file in our build artifacts. Both seem to deploy and run the same on a Tomcat server.

• What are the typical reasons or use cases for having two different WAR files, specifically a plain.war and a standard .war?
• Are there any benefits or scenarios where this distinction is necessary or advantageous?

Any insights or examples would be appreciated!
