Fireflies add nice ambience, can lead to addition of easter egg

It is completely understandable that the development team decided against adding fireflies to the game due to lack of purpose due to the original purpose being invalidated. However i would like to contest against that decision as fireflies had other purposes as well.

I believe the following reasons justify my argument/suggestion:

-Fireflies add a very nice ambience to the swamp biome. One can see the a small lights[not a real light source] flying in a swamp in the middle of the night, making it a lot of peaceful

-Adding fireflies would also allow the addition of ambient noises, that may make the swamp a little bit creepy

-As the swamps are dense, being able to hear the frogs croaking and the light buzzing of fireflies would greatly help the way one views the swamp biome. 

-It would be an interesting easter egg if a frog is given milk/potion of regeneration, they become the AI starts eating fireflies for a duration of 10 seconds because they would have poison immunity

-As others mentioned, a feature regarding making a firefly lanterns is an interesting concept[one can make a random redstone pulse generator by placing a observer facing it. Number of fireflies indicates how strong the output pulse would be]

Thank you for patiently reading my reasons and suggestions
