For anyone who cares about zsh startup performance, `zsh4humans` by `romkatv` (author of powerlevel10k) is worth a look: https://github.com/romkatv/zsh4humans

It achieves instant startup by rendering the prompt before the full shell initializes. Since adopting it, I am done fiddling with my shell config and the fact that `zsh4humans` is in maintenance-mode is actually an advantage as it keeps me from wasting time refactoring `zshrc`.
