So the assumption here is that developers will continue to choose native
over web because of the .3ms spent on hit testing during pointer movement?
I think that's really far fetched. I've met many many developers who prefer
Pointer Events over Touch Events, but less than a handful of developers who
prefer Touch Events over Pointer Events. I can't imagine that many
developers are concerned about the performance hit in this area over
developer ergonomics.
