It still doesn't federate. Not automatically at least. I could load it to sh.itjust.works manually, although it may not federate upvotes, and comments will likely also be manual-only.
But yeah, it's not visible on lemmy.world.
(Pasting post/comment URL from source instance into search can be used for manual loading.)
I was able to load this post here manually, but not on lemmy.world.
