Well, you can vendor, or you can have an internal mirror/cache of repositories.

Force pushes - by far more common than straight-up repository removal - are handled without problem; we let you stick with your old version. (At least, that's how it should be - there might be a couple more test cases to write. I know I designed for this problem early on).

Repo removal, renaming, or whatever, are still problems, for sure.

Today, dep populates vendor/ with dependencies, and works equally well whether you decide to commit them or not.

Not if there is a central repository which doesn't allow removal of packages.
