That's a good reason to diagnose the declaration, but this makes the usage diagnostic very chatty -- if someone forgets to enable the extension, they'll get a diagnostic for each time they use the type and each time they declare something with the type, and there are likely to be more uses than there are declarations. No need to drown the user in repeated messages, so I think the diagnostic on usage should be disabled. WDYT?
