FWIW, this is what I've done in zsh4humans. An attempt to source
.zshrc results in an error message with a suggestion to use `exec
zsh`. It doesn't actually run the command so users who understand the
subtleties can run something else. This has worked well so far. I
regularly receive bug reports against powerlevel10k from users who run
`source .zshrc` and expect the same results as if they restarted zsh
but I never get those from zsh4humans users.
