Along with this we provide a `--no-input`. Both of these are consistent
with other commands.

I agree this should be another ticket, and I also agree overwriting
without any warning feels like an antipattern. I would definitely go with
(1).
Having said the above, are you positive overwrites are happening? If so,
could you please provide the sequence of commands that would trigger that
situation in the new ticket? Thanks!
