any plans for the proxmox team to add fast_dedup to ZFS soon? tried enabling and got an unsupported by kernel error.

as the title says, i am curious if the proxmox team is planning to add support soon, as currently it doesn't seem to be included and from what i have seen online the feature for fast_dedup nearly nullifies the penalty for deduplication compared to the massive impact the old way has, which would be wonderful.

(i believe it only applies to new dedup tables so new datasets haves to be made, etc to utilize it but it would be worth it since the old way has such a monumental impact on performance)

as detailed here and many other places:

specific kernel error i am talking about:

zpool set feature@fast_dedup=enabled twelve
cannot set property for 'twelve': feature 'fast_dedup' unsupported by kernel

It's going to require ZFS 2.3 or 2.3.x, which hasn't even made it into the Test repo yet. No idea what they're waiting for.

there seems to be quite a few new features in 2.3 that look pretty good, i can't wait for them to add it.

i have seen a few people posting about issues on 2.3 while reading up on ZFS more, but it seems a lot of them have been resolved, maybe they are just waiting until the issues get patched up before taking the time to move it over to proxmox so they don't have to keep changing things when patches come out and dealing with the issues that come with new features.
