Actually Tess does not straight up say they will never be re-released in that post. Just that Store Pets are to be treated as a separate thing and that selling old NON store pets would be an unfair advantage. Also note her post was directed to those that could not buy c$, to not feel bad you didn't get them as its needed for site support.
Shian, there comes a point where store pets become so scarce that no one will ever have them. That exclusivity is great for value growth and maybe even a sort of status symbol. But it is terrible for preserving their existence. At that point, they aren't prizes anymore, they are forgotten relics no one bothers to pursue. Cause who could afford it? I am all for store pets re-release to keep them from going UO (Unobtainable). Too many games out there toss out exclusivity objects/pets like it was going out of style. At least some games are more reasonable where restricted things are concerned. New generations should be able to enjoy those old pets. Not 99.9% of the dead accounts no one uses anymore.
Although this would probably result in a topic lock, I am going to say it. This should absolutely be considered later on once the pets become near impossible to get.
