[Python-Dev] How official binaries are built?

Hi, all. I want Homebrew uses `--enable-optimizations` and `--with-lto` option for building Python. But maintainer said:

Given this is not a default option, probably not, unless it is done in upstream (“official”) binaries.

https://github.com/Homebrew/homebrew-core/pull/45337 Are these options used for official macOS binaries? Is there official information about the build step of official binaries? Regards, -- Inada Naoki <songofacandy@gmail.com>
