Polkadot is currently using the default UmpSink () which just drops incoming messages.
This default config blocks teleports from Statemint to Polkadot.

To support XCM from parachains to the relay we need to configure it (e.g. to XcmSink) so it executes the messages.

Not yet; aim to get this in in January once parachains have been running a while without issue.
