I don't think BTRFS has ever been considered stable.
I think they just said: "The on-disk data structure is stable" and lots of people misinterpreted that as "the whole thing is stable"
A stable on-disk data structure just means it's been frozen and can't be changed in non-backwards compatible ways. It says nothing about code quality, feature completeness or if the frozen data structure was any good.
The finalization of the on-disk data structure came soon after Btrfs was announced and happened before 2010. I meant that by 2010s when Bcachefs started development, Btrfs was considered a supported filesystem for "big name" server distros such as Oracle and SUSE.
