Yes.  And the ANSI C spec also makes structure assignment internally
self-inconsistent, forbids using pointers out of the allocated range even
for comparison and so on...

That doesn't create an excuse for doing these things, and doing them breaks
lots of code and annoys people. You'll figure this out when you try and
push it in a product people pay for, and also that just about everything
the idiot macro hack does can be done by a 1 line of perl search of the
source trees.
