I believe Andy noted that it's way easier to find contributors for the self hosted compiler. If someone is passionate about the language, they want to write the language, not C++. And specifically for languages like Rust and Zig, the explicit orthodoxy is that the language is a better successor to C++/C. If you're spending your time telling people that they shouldn't write C++/C and should instead write your language, you probably should put your money where your mouth is and switch the compiler to your own language. Note that this is significantly less common with high level languages. Ruby, Python, even Swift are not bootstrapped. That's because none of these are claiming to take over the systems software niche and therefore don't need to prove anything by bootstrapping.
