Comment 1 for bug 1237550

Thanks for the suggestion, and sorry for the long delay.

Since you filed this bug, the build resources available in the Launchpad build farm has increased very substantially, and it's now quite rare that a few stray builds from an excess recipe would be of any concern. As such, I don't think optimising this by excluding some projects from recipe creation is likely to pay its way. Of course, feel free to report junk recipes to us (https://answers.launchpad.net/launchpad) and we can delete them.
