Unable to delete launchpad PPA

I created a PPA called trafficserver. I needed to change the GPG key used for signing, so I decided to wipe the slate clean and remove the PPA from my account to recreate it. It quoted me something like 1 hour for the average deletion process. I had time, why not.

After about 5 hours I asked in the #launchpad channel about it, and someone reported they had a few PPAs over a year old that were still in the same grayed out status mine was in. Another helpful voice noted that I could re-enable the package by appending /+edit to the URL and recheck publish and enabled. So I'm back there, at least.

I was hoping to use this PPA in production and need to be sure it won't poof at a later date. Has anyone experienced this and knows either if I'm safe to continue as is, or if there's a proper method available to purge the aforementioned PPA? I'd prefer to purge it, but if that's not possible, then at least looking for reassurance I'm safe to continue as-is.

Thanks for your time.
