Back before July 2015, we had a [different close reason](http://askubuntu.com/tools/question-close-stats) for bugs:

![Bug reports should be submitted via Launchpad so that the developers are made aware of them.][1]

Honestly, I think something like this would be a better version of the current close reason for bug reports, unreleased software, and feature requests. Perhaps something like:

> **Bug reports**, **feature requests**, and questions about **unreleased software** are off-topic on AskUbuntu. To report a bug or request a feature, [contact the developers](http://askubuntu.com/questions/5121/how-do-i-report-a-bug).

Ideally, the link present in that post would point to a more canonical answer on how to report a bug/request a feature for both Launchpad and non-Launchpad projects. However, that can come whenever needed
