Agree, but most of the time performance matters less than people think.

In all my years as developer, even back on Spectrum, MS-DOS and Amiga, I never bothered turning off bounds checking and it seldom mattered for the type of applications I was writing.

The very few times it mattered, I was writing big chunks of Assembly anyway.

Everyone thinks their applications have the same performance requirements as Microsoft, Apple, Google, Facebook, CERN, Wall Street, Sony ... have, but they don't.

It is like the native code version of going web scale on day 1, when everything that one has are a few pages to display.
