Don't you think we might be "overthinking" this problem if we are
going to start doing things like telling the user "I know you told me
to delete these files, but I am not convinced you really want to do
that, so I am not going to. Use --force to tell me you really meant
it"

I understand the problem you want to solve, but I think your solution
is worse than the problem and I am not sure the problem is truly
solvable. I also start thinking about graphical environments and
there are times where we want to run API's in response to some
action/event and not interrupt the user with additional UI. If I
cannot rely on delete doing a delete, then I either have to always add
the --force option when I call the API, or I do have to interrupt the
user with extra UI.

I just do not think this problem rises to the level of something we
need to try to solve.
