Any such command would have to be a shell builtin; "cd" can't be
implemented as a subprocess, because it needs to change a property (the
current working directory) of the shell process calling it.  It's also
the sort of thing that would tend to attract requests for options, such
as "-p" passed through to "mkdir -p".

I'm not the bash maintainer, but the bar for new shell builtins is
rightly high since any additions would affect all systems, and I would
expect this to be refused since it's easy to implement it as a local
shell function with whatever behaviour and spelling you want.
