LGTM!
but what about astar & shiden weights?

[ashutoshvarma]

@Dinonard just a suggestion to add the dummy keep_alive bool in extrinsic signature to make sure it's not a breaking change when we switch to upstream version

LGTM! but what about astar & shiden weights?

Local and Shibuya use custom pallet-balances weights since we have integrated account unification into them.
For Astar & Shibuya it's not the case, so we can just reuse plain weights from the pallet crate itself.

Sure, why not!
