Enhancement Proposal
Charmcraft on edge has shared caching (https://discourse.charmhub.io/t/upcoming-charmcraft-changes-and-a-call-for-testers/12175), and it would be nice if the cache option would include that cache directory. The easiest form would probably be setting CRAFT_SHARED_CACHE and then caching that directory like you do with the lxd backup)
