Pointing to programs written with design flaws caused by the flaw in the programming language does invalidate the claim that the flaw exists and negatively affects those programs.
You can write any program in COBOL. Most people would say that it's an insufficient language for doing so.
"Insufficient" here obviously does not mean that it's impossible to write non-trivial programs, just that they'll have bad code.
