As Rawalanche said, it really would be great if we could get a bit of context as to why this is a complicated issue for Epic (for what it’s worth, this is more general feedback than just w.r.t. this specific topic; Epic has a knack for saying what they’re doing but not why, and it makes it hard to feel sympathetic towards the issues presented).
From a user-perspective, it feels like this would just a matter of changing the default in the next major engine version (i.e. 4.27, 5.0 EA2).
I can understand the potential concern of it breaking existing projects due to plugins suddenly being disabled, but I feel like it should be possible to work around that? On top of that, it’d be major engine version change; make sure to mention the changes made to default plugins somewhere prominent in the changelog, and I feel like people would live with the fuss of making sure their projects are set up correctly if they migrate…?
