Prediction of UTXOs lifespan & categorising them into different types

[Shymaa-Arafat]

Since u have worked in Merkleization of UTXOs in2016/2017, r u aware of these results by Stanford University & others?

.
Also, the burden of burned UTXOs?

.
What do u think about putting each type coinbase, burned,... etc in a different tree or whatever data structure used to shorten the proof size?
