Because the coordination required for updates of a shared cache massively complicates things.that should be fast enough to check out. Libraries are cache, and it's best to avoid sharing caches whenever you can.Why?
In particular, for your scenario, the removable storage will need to be mounted with the same device number every time, or else you'll get "corrupt library (failed inode signature validation)". Libraries weren't designed for sharing. Cacherevs were.
In general, caches are a shortcut; a necessary evil. They pretend to be something they're not, which is fine as long as their imitation is perfect. But if they behave even slightly differently, all hell can break loose.
