The overhead and complexity of a dozen different IDEs, JS frameworks, 4 browsers, 2 mobile phone platforms, etc etc is less complex?

In a day to day engineering perspective it’s all a mess of abstraction and indirection anyway?

If we’re going to optimize ONE stack, I’d prefer the one with all the optimized rendering and input mapping, rather than hacking that all into a bloated document parser like we’re hacking into a browser?

IMO that is textbook functional fixedness.
