Yet CloudFlare went further, disabling them over TCP as well. I'm a 
little disappointed by this as they're certainly a timesaver when 
troubleshooting (although I suppose that doesn't make any difference to 
them)

Personally, I hope that dig revolves a new fakeany option that simply 
fires off each possible QTYPE separately and merges the results (and 
it's not that hard to script, but it would be convenient to not need to 
drag around yet-another script)
