Hmm, part of my "cdup" shell function looks something like

     cdup () {
	... error detection etc...
	d=$(git rev-parse --show-toplevel)
        cd "$d"
    }

so I can quickly go up to the top-level.  With "root", I could
replace that rev-parse call with "git root", but I'd keep typing

	$ cdup

after doing so anyway.  I am not sure how much value it adds.

You would need to handle error cases like "you are not in a working
tree", you cannot expect to be able to say

	$ cd "$(git root)"

anyway.
