Yes, and all the counter-arguments here continue to miss that very simple point. 
That point was made in the first post about this topic and it's still not 
acknowledged - let alone addressed.

This breakage is unnecessary and retroactively goes back 130,000 commits. A warning 
combined with not issuing the debug symbol would be just as fine and would still 
result in valid output.
