Fiddling with br has never worked and never will work ... very stupid move. (changes like these shine a VERY bad light on cryptocurrencies and what they really stand for)
The very only thing I would vote for is ProgPow but apparently people are way too dumb (or have an agenda) to bring that up.
Well EIP-1559 will go in July fork and it's finalized. PoW will replaced with PoS withing 1 year or so. (And this final too)
With EIP-3368 it ensures the "smooth" transition from PoW to PoS. (IOW, not a massived hashrate move to other coins and leave Ethereum "unprotected")
