Comment 31 for bug 1460222

@Russell, thanks for clarifying...that's why I say 'potential', as I was not sure :)

For User defined metadata that are oblivious to backends, I think we are all in agreement that they are a non brainer. In fact [1] was along those lines and it didn't get it only for lack of time.

As for your other comment, it sounds to me that the very nature of the problem we're trying to address makes incredibly difficult to come with a common ontology that can fit to the majority of the backends involved and use cases.
