Currently, every subcommand of try-runtime operates on externalities with StateVersion(1) (which is the default for RemoteExternalities - https://github.com/paritytech/substrate/blob/master/utils/frame/remote-externalities/src/lib.rs#L269). Although it will work with any remote chain without any warning or check, some problems may rise if chain uses another state version. For example, Polkadot (afaik) and AlephZero use StateVersion(0).

This PR introduces new CLI option which enables user to specify target state version. By default it is StateVersion::1.

also, would you @bkchr / @ggwpez / @kianenigma support either of these two ideas?

  1. easier runtime passing - currently, we have to provide whole chainspec (to every subcommand) containing the target runtime; then the whole genesis is built, only to be discarded after retrieving runtime code; I would propose passing path to a compiled wasm blob

  2. keeping continuous connection with the chain - currently, for each block we have to reconnect to the node:

2022-08-22 12:22:43.710  INFO                 main jsonrpsee_client_transport::ws: Connection established to target: Target { sockaddrs: [], host: "localhost", host_header: "localhost:9944", _mode: Plain, path_and_query: "/" }
2022-08-22 12:22:43.710 DEBUG                 main try-runtime::cli: new block event: 0x35143cc9d8afc7be8238cc4f989168bc8c9b237cddea67356e4648acbeeac774 => 65, extrinsics: 1

When the blocktime is long, it makes sense obviously. However, for a short period (like we have in Aleph and possibly in Polkadot) it would probably be better to keep a single connection for the whole interaction. However, I'm not so sure whether this is feasible / worth doing.

of course I'm willing to take up any related tasks

I think both of your ideas makes sense, but they can and should be follow-up PRs.
