I'm less familiar with this area, but when I clone I get a pack *.idx file, why does it need to be regenerated?

But yeah, in principle this would be a sensible addition, but I'm not aware of cases where clients get significant benefits from bitmaps (see https://githubengineering.com/counting-objects/), and I don't turn it on for clients, but maybe I've missed something.
