This is a useful feature in some situations: https://releasenotes.docs.salesforce.com/en-us/winter19/release-notes/rn_sales_features_core_oppty_sfx.htm
But this can literally double the share table footprint, right?
And so now we have 2x performance hit if the role hierarchies change for both "owners" (current and previous) at the same time? I want to make sure I use this feature responsibly - with caution - in large orgs.
Am thinking about the potential performance implications correctly?
