I have read about EIP in the past months too, and believe it will be a useful feature for ETH. I have no idea about the technical side, but a burning in the supply will surely increase the attention to the project and its price. Remember, when ETH2's testnet was announced, its price was pumped a lot. EIP1559 may not be an ETH2, but when prices are not so good, this little news will attract many.
