The "only" thing that change was the consensus algorithm.

That's good software engineering practice when you have hundreds of billions at stake. Minimize the bug surface.

Furthermore there are other concerns, Ethereum prides itself in running on the most modest of hardware. Many stakers are staking on Raspberry Pi 4.

A blockchain with large transaction speed require very powerful machines. It becomes impossible to sync with less than 1Gbps of bandwidth and storage cost becomes prohibitive.

Doing so before implementing state expiry/rent to reflect the cost of storing data in a blockchain will reduce decentralization as hardware requirements require professionalization of node operators.

Furthermore there is the rollup-centric roadmap for future scalability: https://www.reddit.com/r/ethfinance/comments/r26hhv/rollupce...
