I wouldn't go quite that far. In PHP, for example, it's still the most straightforward way to use dynamic sql statements built up as concatenated strings. It's easy enough to skip input sanitation here or there on accident.
That being said, there's absolutely no excuse for that sort of slap dash engineering today. It's dead simple, even in PHP, to use input sanitation, or to use parameter binding / prepared statements to avoid SQL injection vulnerabilities. Those sorts of best-practices have been well known for at least the last half decade.
