    I'm trying this in 2020.2.0b12.3574. Instances are still recreated when modifying anything in the inspector and then doing ctrl+z. Is this because of the Unity version I'm trying? I wonder what's the proper protocol when the issue is marked as fixed, but it's not completely solved. If this is already supposed to work in the version I tried, I'll submit a bug report with a project and see what happens.

    Thanks for confirming the 2019.4 support! Any ETA when it will be ported? It's been "Fix in review for 2019.4" for almost 2 months already.

    Why it's no longer planned to be fixed in 2019.3/2019.4 and been removed from the known issues list in 2019.3.15 changelog today? I was really hopping it'll be fixed in 2019...
