You bring up a good point. In most cases interoperability is not required. However, assuming it find enough adoption, having a standard format would likely make many things easier, like switching languages, or moving parts of the application logic into the database layer. Think of json support in databases these days and how it enables versatile use across applications. Another benefit would IMHO be the possibility for a simplified API for developers. Many engineers don't know what AEAD or block cipher modes even are. Providing a simple encrypt()/decrypt() function that would work across applications would be awesome.
