We don't need them anymore.

[Picothea]

I only learned about them bringing back the feast rewards today, and just wanted to drop by to say I feel the exact same disappointment as the OP. I worked hard to earn these during the first 4 seasons of solo feast. Didn't always succeed but that's fine, skill issue.

Since they're already making old exclusive rewards obtainable, when can I get 1.0 rewards? Never I guess? But it's the same thing - an exclusive reward.

But that's the thing - Some 1.0 items have come back before, particularly the White Ravens as replicas. If there's enough of a player demand to bring the other items back, I wouldn't guess it's impossible. It's just that most players don't notice a tattoo on your back or one specific chocobo with a unique barding.
Feast items, on the other hand, are very distinct. Many players who see them immediately look up where they can be found, especially due to the glamour restrictions we're moving out of.

You should ask yourself this, though: Do you actually want the 1.0 items? Or are you just commenting because you dislike the idea of others having replicas of something you had for years?
If you're actually interested in 1.0 items, go ahead and advocate for it. I for one have no complaints.
