What to do with 0P giveaways?

I made a giveaway for a 3P valued DLC for a F2P game two years ago that was later removed from Steam and the value was dropped to 0P. I submitted a ticket when it happened and was told that it was a low priority and something that only cg could fix but with the recent feature of allowing giveaways for no-value games I have been waiting in anticipation that this will be corrected. Two years is a long time to wait and it was something that I had actually paid full price for but I have hope still though I am curious to see if you can find out a way to get something done sooner.

• Updates to how we sync game prices with Steam, which should result in games keeping their value when they're removed from the Steam store, instead of changing to zero value.

It's been fixed but doesn't appear to be retro-active

Bump because I still want to find a solution.

So, question is - should I make a support ticket "Add Game to List" for such games, even if don't plan to giveaway it now, but made a giveaway someday in the past?

if you made a giveaway someday in the past, doesn't that mean the game is already on the list?
I'm confused

since the guidelines says

All questions and concerns should be directed through the support system on the site, and we ask users not to add support members on Steam for help.

I guess it's not a bad idea to create a ticket if you have an issue with what's going on
