If there is still no change in July. I think it will be fatal to the development of Ethereum.
It should make a lot of platforms being forced migrate to the new blockchain with a better scalability. People are feeling good with ethereum caused by the system is so simple and it will make the development to the platform is so easy.
The problem is if ethereum dev didn't expect there would be a very big demand for ethereum platform like this time. There must be a definite solution for this.
EIP 1599 is the only best solution to fix the scalability problem.
