if the server is started with -D NO_DETACH , no PID files should be created and the PidFile directive should be ignored.

Modern init like systemd have his own process indentifier tracking capabilities and by design cannot "forget" what the process ID is neither crazy childs can escape its control, in such scenario, pid files are completely useless.

"httpd -k reload" etc rely on reading the pid to signal the server.  You could remove "httpd -k" support entirely, drop the pidfiles and make a very pure systemd-only-controllable service; this might be worthwhile tho a bit of a culture shock.  So I'd say patches welcome - but the code is working as designed currently.
