Because the coordination required for updates of a shared cache 
massively complicates things.

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.
