My point is that it's easy to accidentally tag a tag. It's not easy to
accidentally tag a tree. The counter example would be something that
looks as easy as your "git tag mytag v1.0.0" but actually tags a tree.
I couldn't think of one.
I do buy the argument that arguing for safety valves from a point of
"what's the easiest mistake to make in our current interface" might not
be the best one. It yields a set of operations that aren't necessarily
sensible or orthogonal with respect to the underlying reality of what's
possible and what's reasonable. Which I think is the point you're
making.
