All people need is a boot-time option. We don't need tcsh, bash, zsh
or any other shell as part of the base system.

The flip-side is the Solaris approach. It's got a sh that can't even
do test -L properly
I think there's a balance to be drawn here, and going
hell-for-leather in one direction is as evil as going in the other.
Having a ``base'' version of {c,}sh (oops!) that evolves with
standards is a good thing.
IMHO adding packages from sysinstall is the way to go.
