Why is Conversation View listed as advantage over Proton despite its workitem still being open and it still being on the Roadmap?

[KernelBypass]

Here conversation view is listed as a ready-to-use advantage/pro of Tutanota over Proton:
https://tutanota.com/protonmail

Despite it still being an open Roadmap item (#6) here:
https://tutanota.com/roadmap

And an open 9-year old workitem here:
#6

Which one is it?

Conversation view is already available, but the issue is still open because we still have ideas to further improve it :-)
