Implement remote locking for xtokens

[Chralt98]

Is there a plan to implement XCMv3 remote locks in orml_xtokens for a simple abstraction?

Would be great to have this, but I am too lazy to do it myself at the moment, because it's not that urgent.

No plan yet. Also remote locking won't be very useful for non system parachains as the tokens are locked in our parachains rather assets hub and I dont' think parachain teams will redo all the work to rebuild the parachains in such way to have the relay tokens stores on assets hub.

Thanks for the answer. I don't understand. The asset hub is Statemine or Statemint, right?

What I have in mind is the following:

A user on Karura locks KAR and sets the unlocker to my custom parachain. Now my parachain can query the locked balance and sees that a user locked KAR and do a token holder vote with those KAR on my parachain, without the need of the user to transfer his KAR to my parachain (trustless).

Right. I see. That will be a valid use case. But Karura will need to support this remote voting as well, which shouldn't be hard IF the governance pallets provided by Substrate supports remove voting (which I don't see any issues about implementing those).
