Yes! Fixing ergonomics of APIs has dramatically improved web
programming.  I'm convinced that concrete proposals vetted by major
library developers would be welcomed and have good traction. (Even
better would be a common shim library demonstrating the impact).

Measuring these changes by the numbers of bytes removed from downloads
seems 'nice to have' but should not be the goal IMO.
