Very interesting. I did the treasure chest emoji proposal back in 2018.

Back then the committee was very determined not to let in more emojis – for the treasure the official response was that Unicode already had money symbols and that this should be more than enough for all use cases.

Looks like they caved in now and just adding more clobbers left and right. Half of me is happy to finally have the treasure chest, but the other half is sad, that somehow now they added it, when we could have had it 8 years ago!

If you had asked me yesterday, I would have bet money on a treasure chest already being an official emoji.
