I use zsh.  It's possible to convince it to be more POSIXy by saying
"emulate sh" or invoking it via a symlink called sh.  However, having
said that, I don't recommend it.  I set /bin/sh to zsh on my Debian
system and a lot of things broke.  Early versions of Mac OS X did that,
too, and they stopped because it was very broken.

As for ksh, I don't know whether you want to kill support for just ksh93
or mksh as well.  I've generally had good experience with mksh as
/bin/sh when I've tried it, and it's at least semi-supported in Debian
because it meets Debian's POSIX-plus requirements.
