UE4 and ARCore

Just wanted to know what are the plans for the ARCore implementation on UE4. The 4.23 preview has it updated for 1.7. ARCore is currently on version 1.10.
The roadmap for the release after 4.23 doesn’t show anything related to ARCore either, so it got me thinking - for AR stuff is it worth it to wait for UE4 to catch up with the versions or should I just simply switch to Unity for that?
It would be very helpful if someone could give any suggestions/clarify this.

I want to know too。
