I tried to reproduce the working solution in the other repo, and I was unsuccessful.

Checked polkadot-sdk macro and pallet_index parsing, I don't see any cfg handling.
But I'm not that good at procedural macros so I might be missing something.

It's fine to close this PR, or ask for help from polkadot-sdk repo maintainers.

@Dinonard I found the issue and a workaround. The runtime macro handles #[cfg] correctly for explicit pallet declarations (with '+' pallet parts syntax) but NOT for implicit ones. Also, I removed optional = true from pallet-sudo, this is needed for macro expansion otherwise I face this error: "use of unresolved module or unlinked crate pallet_sudo" (another bug in the macro). I will open an issue in the polkadot-sdk repo, but this solution works for now, PR is ready for review.

@Dinonard cargo update done ☑️

@ipapandinas sorry, that was a question since I noticed PR has huge amount of LoC updates, and then I saw it's becaus .lock file is updated.

I don't think you should do it, in order to minimize the changes.
Right now this changes literally everything.

I misunderstood it, maybe I did a cargo update during my tests, it's reverted now
