[twoseat]

Metadata is out of experimental status. Customer request.

I too have a customer asking for this functionality.

Support for metadata has been added in several places. Apps, Spaces, Orgs, etc...

I'm going to close out this issue. If you missing metadata on a CAPI resource that supports it please open a new issue fo that specific resource and we can address it. Thanks.
