In general that is the proper form -- but this particular issue is

Some users (like Bluehost) require the functionality of symlinks without the possibility of server side vulnerabilities. Having the vulnerability documented doesn't keep servers safe. The patch I submitted allows httpd to use symlinks in a protected fashion that doesn't allow for users to serve arbitrary files.

I'll go ahead and submit a more detailed email to the security. More feedback from the devs is appreciated.
