FWIW performance is not really in the picture when I say "I wish everything was Bazel". Configured properly, CMake and Make are probably unbeatable for speed.

It's just that I really really hate maintaining Makefiles and CMake configs.

Admittedly in the latter case it's because I have never grokked CMake, but also... I don't want to grok CMake, I grok a perfectly good way of building C++ already. And it can also build Go and Rust and Typescript and Proto and JSonnet and it can run my janky codegen shell scripts and if we migrate to Carbon it will build that too and I won't even have to read the documentation.

Not saying I think everyone should migrate to Bazel (I hope I will not become That Ex-Googler), just explaining where the urge comes from.
