Allow generic XCM execution #1283

Following this post on the Polkadot forum: link

I would like to suggest allowing generic XCM execution on the Kusama system parachains. Kusama already supports this so I don't think it would be a crazy idea to allow it.

Some clear benefits of this would be:

Possibility of transferring reserve assets on AssetHub into an account from a remote chain.
Possibility to do two-hop reserve transfers.
Doing native token transfers with XCM. This could make it easier for wallets and other UIs to do non-cross-chain transfers since they can rely on using the XCM standard for doing this.

This issue has been mentioned on Polkadot Forum. There might be relevant details there:

There are still some things that need to be fixed. We cannot do this yet - same why it is also not advised to do so for any other production parachain.

But we can do something in the relays https://github.com/paritytech/polkadot-sdk/pull/1303

This is now allowed on all test chains (all chains in this repo), as well as on all Kusama chains: https://github.com/polkadot-fellows/runtimes/pull/261. Polkadot chains will come a bit after Kusama as usual.
