Support stripping dropped instances from manifests when making sparse multi-platform copies about image HOT 3 CLOSED

Thanks for reaching out.

This is the intended, or at least as-of-this-point-frozen, behavior; e.g. #1483 (review) points at a specific constraint.

The alternate, of copying only a subset, and modifying the manifest list (at the price of breaking digest references to the manifest list), is a reasonable feature to perhaps add in the future. (And nowadays we have some ways to make the compatibility constraints mentioned in #1483 less constraining, e.g. c/image/internal/private.)

#1707 will allow modifying the manifest list.

The RFE to copy only some architectures, and to update manifests, is also tracked in #1687; please follow the progress there.
