Sure, Jamie is concerned about the practical consequences. If your response to Jamie's 2019 bug report about X in WordCount was to close the ticket because you rewrote WordCount as WordCounter even though you've got no reason to think that might fix X, that's CADT. You are wasting his time. Don't use a "bug tracker" this way just write "This is broken garbage, I don't care" so that people know what's up.

I don't see that nonsense with the programming languages. Even something egregious like provenance. There's a problem, neither C nor C++ make any actual sense on a vaguely modern computer as described if pointers are just machine addresses. So the compilers invented "pointer provenance" to explain why what they actually do is reasonable - but no such fix is actually endorsed in the Standards. A defect report was raised in, I think, 2003. But it was never repaired. Nobody is under the impression that C++ 11 magically means this doesn't count, they didn't fix the problem, it's still there, and in C++ 14 and C++ 17 and C++ 20. It's even there retrospectively (this seems to be controversial for some reason but it's obviously true) in C89 we just didn't realise.

Under CADT the C++ committee would say, well, C++ 20 is new, you need to write a new defect report if you claim it's still broken. But they don't suffer CADT, their problems are altogether different.
