Enacting this proposal will register the asset { parents: 2, interior: GlobalConsensus(Kusama) } on the Polkadot Asset Hub. KSM will be a sufficient asset with a minimum balance of 0.01 KSM.
The "owner" of the asset is the account ID conversion of the path (expressed as a Multilocation) to the Kusama Relay Chain, i.e. the governance location of Kusama.
This registration by governance is part of the initialization of a Polkadot <> Kusama bridge. Future assets that are sent over the bridge will not need governance motions from the system Root origin. There is a similar referendum to register DOT on Kusama.
A note about metadata: I discovered while testing that force_set_metadata is not included in the SafeCallFilter, so it cannot be executed over XCM. This will be fixed in this PR. A follow up referendum can set the metadata (name: Kusama, symbol: KSM), however this is not necessary for functionality (and the asset identifier itself is expressive of the asset meaning).
