It may sound like an odd question but is there any way to demote a package in Extras-Devel.

I submitted a breaking change last night that caused a mini furry of posts that the application was broken, along with proposed workarounds. Unfortunately, it was reasonable that the version I submitted would cause a break (this is what I was trying to test)

While I post a new version up to the auto-builder, can I remove that previous version? so that no one else installs it?

or is there a way to mark a release as a Development only release that does not force a version update on users?
