This makes sense and would probably give EIP 3074 campaigners pause if it was really about user onboarding and UX on L1.
I’ve argued elsewhere there’s a simpler explanation for why none of these arguments seem to land: that EIP 3074 is an example of a special interest protocol lobbying effort designed to benefit Consensys/Metamask.
EIP 3074 was shot down in 2021. It only regained traction after Matt the author moved from Consensys into the Geth team and started leveraging Geth’s position as the majority execution client to social engineer support from the other “core devs”. Other execution client devs don’t want an adversarial relationship with Geth. Behind the scenes Matt discourages work on native AA, speaking on behalf of the Geth team saying they won’t support it. In public he laments how we’re not making progress on UX because “core devs” don’t care about users. It’s quite cynical.
