I found that there is an Potential Duplicate Lightning Component (Standard) available for Lead, Accounts and Contacts. The components has also a merge process build in. This is very nice and important for Data Quality. However this component is not available for any Custom Objects or other standard objects. The process and the logic behind this should be very similar for any objects.

The components is the second in the right panel – the one with the yellow icon and the bold text.

Here is the documentation on that feature: https://help.salesforce.com/articleView?id=duplicates_existing_setup.htm&type=5

We have already created a custom lightning component for any objects (pink icon with the bell), but it is still buggy and the merge process is incomplete. Especially the merge is a lot of work and I found a strange behavior on DuplicateRecordItem (this is elaborated in this question here)

I want to plan ahead and avoid wasting time to create things which will eventually become available as standard.

So I would like to know if there is an update for this components on the roadmap which will be usable in the same manner, but for all objects – standard as well as custom? Any hint under Safeharbor is highly appreciated.
