So what? Isn’t that what kernel development is all about? The careful detailed stuff goes in kernel space so that if you want to make a mess of things in your application you can do so without bringing down the whole system. It’s not like that to hurt your feelings or make you feel “excluded”. It’s for the greater good.

You don't need an exclusive community to make that work. We as an industry have tools: fuzzers, testing frameworks, better programming languages and type systems, and proof assistants, all of which will do a better, more consistent job of ensuring quality than project leads being assholes.
None of the techniques you’ve described is either proven or applicable to this domain. Being an asshole while unpleasant is not incompatible with “getting things done” as has been shown again and again and again.
This line of thinking is a fantastic way to create a non-inclusive group.
