I've rebased it now, see attached.

We had this discussion already, and back then I was against dropping it
as well.

Do you see --progress being the default? I don't think this is in-line
with other project binaries, so I guess not?

If not, I guess your main point is that we might come up with a better
implementation/UI further down the road. Which is fair enough, but I
don't think this is such an in-your-face feature that changing the way
it works in future releases would be a terrible breakage of backwards
compatibility. Even more so as it is solely an interactive feature and
cannot be used in scripts etc.
