Could you show any example? I don't care whether it's on mainnet, testnet or signet.
Since coin-age priority was never part of Bitcoin protocol,
1. Do you think it's possible to enforce it on Bitcoin protocol? Currently miner/pool can mine empty block and choose any transaction.
2. Most miner/pool will be hesitant to support this change.
also coin-age is part of code. its a simple: current blockheight - utxo blockheight = coin age
and also miners in the first few years did obide by a different fee formulae than the current weight cludge
enforcing it is the same as how pools obide by the weight (vbyte vs byte) formulae
While coin-age was part of code, it was never part of Bitcoin protocol. See
https://bitcoin.stackexchange.com/q/54583.
I see, but we know it's more than removing the "weight". Since it require hard fork, it'll force many people to upgrade their software and another activation signal which will take some time (IMO at least 6 months is required) and attract another controversy (such as cutting backward compatibility).
backward compatibility.. ? how many people are actually running nodes from pre 2017.. i bet its not 5% of network
also the march2017-august 2017 proved that mandated activation can happen. (bip148 and bip91)
I'm aware about low percentage of node which use client that doesn't support SegWit. My point it'll be one of reasons against hard-fork.
