I didn't use PGO and that's why GCC didn't know which part is hot. Maybe, pymalloc performance is similar to mimalloc when PGO is used, but I had not confirmed it. While Linux distributions are using PGO, some people use non-PGO Python (Homebrew, pyenv, etc...). So better performance without PGO is worth.
