I've found someone is trying to close this question as off-topic since it concerns Apache HTTPD on Stack Overflow. If it weren't for the fact that a highly-rep'ed user is arguing for it, I wouldn't be asking this question. I frequently see questions concerning Apache and .htaccess on Stack Overflow (over 27,000 are tagged Apache). I consider it a software tool commonly used by web programmers, and therefore on-topic, based on the Help Center.
However, they are defending it based on a small nuance in the close reasons: "Questions about general computing hardware and software are off-topic for Stack Overflow unless they directly involve tools used primarily for programming", saying HTTPD is primarily for web server configuration.
How closely should a tool primarily for programming be enforced and where do we draw the line?
