This config is used only for perf stuff, cruft

👍

lets introduce breaking change entry for that in the CHANGELOG, because, in fact, this change implies potential breaking changes in rendering behavior (as Fela's major version is updated)

We had prev here spreading all props, not just the render, not sure if there were other props here, but it may be worth taking a look...
