I suspect @lilles did that because if we allow parsing arbitrary identifiers for future compat, then you need to keep some kind of hash set of strings or such while parsing the property, to know if there are duplicates (since the engine doesn't have any internal representation for those)...

But I'm not sure why parsing arbitrary identifiers is ok, it seems undesirable, at least from the `@supports` and such point-of-view.
