No, it doesn't.  Bourne shells never have.

I prefer not to litter the builtins with --help and --version, given the
presence of the `help' builtin and $BASH_VERSION.

`help cd' says:

        [...]
    The -P option says to use the physical directory structure
    instead of following symbolic links; the -L option forces symbolic links
    to be followed.

If you want such behavior, it's trivial to write a shell function to do it.
