So, in the latest snapshot, we got the golden dandelion, which can be crafted using gold nuggets and dandelions. I think Mojang slightly missed the opportunity to update the Sniffer, which currently has almost no use beyond giving players flowers to decorate their bases.
I think that if the golden dandelion was obtainable with the help of the Sniffer, many players would become interested in finding it, which would make players interested in archaeology again and the Sniffer itself would become more valuable
