It's evidence of a really immature business. I previously worked at <place bring in a lot of money from people using their site> specifically doing optimizations, and we were well under 1 second to do most things, but we could measure a 10ms improvement in dollar amount revenue gain through A/B testing. With the framework in place to claim dollar credit for microoptimizations we happily had many many engineers working to improve it. The fact that Valve has nothing of the sort after years is embarrassing and untold amounts of money has been left on the table.
