[images] faster incremental blob publishing copytree was only used to produce the blob output directory. The blob output directory is content addressed, as such repeating writes to target locations is not useful work. The code for copytree is used to produce a copy-only-once behavior that significantly reduces total number and cost of io operations for incremental builds.
