I have no strong opinion on whether to use the name-field here or not.

Using the name-field rather than adding a new one could perhaps be
less confusing to current parsers.

But if the interface is considered stable (and some people do) you would
not be able to add anything here. This *is* a real issue, but I'll defer
this one to Linus and Alexandre.

Perhaps we should just leave things as they are.
