Hi team, Alex on the duplicate management team here.
We are well aware that we need to extend our duplicate management checks to fit the entire data model. Our current plan is to up-level our existing toolset within our current scope of support objects, before we extend to begin supporting the full data model. Once we have improved duplicate detection, better bulk handling, and a way to create an automated process around resolving duplicates, we will 100% look to expand to other parts of the data model.
Because we are not planning this immediately, I’m marking this idea as not currently planned – but know that it is definitely on our radar and something we want to support in time.
