I run 48 Lido CSM validators, alongside a few solo 0x02 compounding validators.
Personally I do not mind letting rewards accrue on my solo validators. But I think EIP-8148 would be really useful for a future version of CSM.
Being able to choose a lower sweep threshold would make 0x02 much more workable for CSM operators. You could compound into more effective-balance increments, but still have rewards sweep automatically at a level that makes sense for you instead of only at 2,048 ETH.
If CSM could work this way, I’d be comfortable running more validators through it. I think that would help bring more stake to independent operators and improve decentralisation.
So from my side: I support EIP-8148 as an optional feature!
