I think we're now quite happy with the reth trait and could start stabilizing this in alloy

some prelim work #2057 which was intended to make rpc conversion easier (wip)

[emhane]

could be nice and easy to start with a trait that doesn't have transaction associated type like this, since could cause some conflicts

[PoulavBhowmick03]

where do I keep the trait in? in the crates/consensus/src/block/traits.rs or crates/consensus/src/block/mod.rs itself? Since there seems to be name conflicts for the BlockBody term used as a trait and a struct in crates/consensus/src/block/mod.rs
