Writing the cache after loading all plugins manually is extremely slow, 
especially on Windows (because PE format sucks so bad). Even now without this 
problem, LibVLC instance creation spends most time recursing through the 
plugins directories, so that will be removed in the near future as well. It is 
only an artifact of the design before the plugins cache afterall.

No we can´t. On most platforms and on any sanely configured system, that won´t 
work due to permissions, and it only makes sense when adding or removing 
plugins anyway.
