I was disagreeing with Santi's "'push --bundle' and 'bundle
create' can be equivalent".  They can't be, as "push" is always
"update" and never "create".  So I do not quite get your "But for
that I think"; I think you are just agreeing with me.

Even if we taught "push" to create (which I doubt would happen
due to its security and administrative implications), it would
not make the two any closer to being equivalent.  For them to
become equivalent, we would need to have "push" unlearn how to
update, which would never happen ;-).
