Can you put this under some feature flag?

I'm fine with not having this on-chain, in the live runtime, but quickly swapping out live runtime with the one compiled locally with the enabled astar-sudo flag can be useful for quick debugging.

I've added an astar-sudo feature flag to conditionally enable the Sudo pallet. However, construct_runtime! doesn't support #[cfg] attributes on individual pallets, leading to compilation issues. I also tried migrating to the newer #[frame_support::runtime] macro, but again same issues.

So I'm using a simple construct_astar_runtime! wrapper macro as a pragmatic solution to keep the code DRY. Happy to rework if you have a better approach or have dealt with feature-gated pallet inclusion before.

What you might want to try is to use the new syntax for constructing the runtime, i.e. the new macro.
It's used in polkadot-sdk runtime template for example.

I did a quick try with it and managed to disable sudo pallet in another project in that way.

Are you suggesting this?

#[frame_support::runtime]
mod runtime {
    #[runtime::runtime]
    #[runtime::derive(
        RuntimeCall,
        RuntimeEvent,
        RuntimeError,
        RuntimeOrigin,
        RuntimeFreezeReason,
        RuntimeHoldReason,
        RuntimeSlashReason,
        RuntimeLockId,
        RuntimeTask,
    )]
    pub struct Runtime;

    #[runtime::pallet_index(10)]
    pub type System = frame_system;

    ...
    
    #[cfg(feature = "astar-sudo")]
    #[runtime::pallet_index(99)]
    pub type Sudo = pallet_sudo;
}

It doesn't compile, I think the entire runtime must be feature-gated:

https://github.com/paritytech/polkadot-sdk/blob/ec03705c977b42995de78fa897ce46fae8f5b402/substrate/frame/session/src/mock.rs#L75-L94

For me it compiled.
It might be due to the newer version of polkadot-sdk though.

The link you provided uses the old macro, and I agree and know that it doesn't support gating on the pallet level.

Don't you also need the XC asset migration for Shibuya?

Correct, I forgot we did some testing for AH in Shibuya too, I have added it now.
