Description

That probably fits nicely with #37 though the difference is whether we can warn developer of delays in runtime. Sort of basic profiling with a recommendation to split animated container from non-animated functional children subtree if we can detect delays and huge number of re-renders.

Not quite sure how technically do that (yet), but could take similar to react-hot-loader approach.

Contributor guide
