Bernd Eckenfels commented on VFS-635:
-------------------------------------

I prefer to have it in core with optional dependencies. Mostly because all other providers d(from commons) do the same. Otherwise the build will get even more complicated. (I do. understand that this results in a bad maven citizen, though)
