Themes use theme inheritance to share code and resources between each other. ... The Gray ("ext-theme-gray"), Accessibility ("ext-theme-access") and Classic Sandbox ("ext-theme-classic-sandbox") themes all extend Classic.
However, when comparing ext-theme-classic and ext-theme-access half are copy/paste.

Are you saying that the mechanism does not copy base theme images for you? Or that we have some baggage in our themes that needs cleanup?
If the former then that would be a serious bug. Resources from base themes are copied to derived themes in the build process if the derived theme does not have a replacement.
I suspect the later because the leaf-most themes (gray and access) have not been combed over to eliminate duplicates. In the end they are just a minor issue because the build would produce the duplication anyway. Still something we will want to cleanup of course.
