If you're curious about viewing the content, it's Base64-encoded gzip string, I was able to view the content through this tool:

To successfully do it, you need capture the string after the last "@" in the string as highlighted in the attached image and paste it in the page.
One might be able to modify the suitecloud.config.js file to decode the XML when the "object:import" action is occurring on import and then run an encode when a "project:deploy" is happening.
I think I might see if something like that can be done in my spare time.
