Push makes sense to me actually, branches and tags are both aliases to a particular commit. What makes them different is that the branch pointer gets updated on commit, while the tag pointer is (meant to be) static.

But I do in general agree that the cli leaves much to be desired. I really have to give credit to magit for making a git ui that is simultaneously easy to use, powerful, and has actually made me more proficient at using the regular cli (the commands that underlie the operations are echoed so whenever I do something new I take a peek at how it's done).
