Shared libraries in system32 are an abomination that should be removed 
from the face of the earth!

More seriously, the reasoning is simple. libwdi is a generic USB driver 
installer, and there's no guarantee that anybody who installs WinUSB 
will use it against libusb 1.0. On the other hand, if you install 
libusb0.sys, you're pretty much guaranteed to want to use libusb-win32, 
so installing the DLL along with the driver makes sense.

Maybe I'll change that when libusb 1.0 supports libusb0.sys, but, if I 
can get my way, that's unlikely, as I'd rather not have libwdi install a 
libusb-1.0.dll in system32 ever, else I'm pretty sure I'm going to end 
up in a situation during development where I'm testing a shared lib 
based app against a newly built DLL, while in fact I'm using the one 
installed by libwdi in system32.

I'd prefer not piggybacking libusb on top of a driver installer. 
Besides, I hope we're not going to fall as low as software makers trying 
to bundle stuff that people might not need, just for the sake of 
promoting stuff they want to promote. On the other hand, one could 
create a libusb installer that includes libwdi, to install both the 
driver and the DLL.
