Listed where? If you mean they're listed as special moves on this site, that doesn't mean anything.
As for whether we could see them come back, I absolutely think we will, it's only a matter of time. There are plenty of people who would be interested in reruns of exclusive moves and that interest is what drives the profitability of the CDs in the first place. So Niantic has an incentive to rerun them at some point for more profit, but they want to make the wait long and unpredictable to not undermine the value of the first CDs where the moves are available.
I could even see them just making a limited amount of CD TMs available in the shop for coins and I know even that would make a lot of people happy (me included).
