I somehow agree with your argument, but then again, sometimes I'm still interested in
*only* the status for a given directory.

IMHO, answering the question "what would be happening if...?" should be  git-commit's task
(e.g. git-commit --dry-run). And git-status should behave similar to git-log and git-diff.

For those interested: I have attached a little script that mimics current git-status
(except the "dry-run" stuff) but also can take a list of directories/files.
