Hmm, yes, I agree that is inconsistent. However, it's such a common
workflow that forcing a '-f' would become meaningless. And you _can_
rescue the blob from the object database in a pinch, though finding it

That's exactly the reason why I mentioned this inconsistency
between add vs rm "tongue-in-cheek".
We really do not want to require -f for common situations so
much that it ends up training people's fingers to type -f
without thinking, which would render the safety option
meaningless.
