Xbox Controllers: Should hid be used?

Other 3rd party drivers (and seemingly Microsoft's driver as well) uses HID to 
describe the [any Xbox] controller's features. We can see uses of this in other 
drivers:

TattieBogle - 
http://tattiebogle.net/index.php/ProjectRoot/Xbox360Controller/OsxDriver

XBCD - http://www.redcl0ud.com/xbcd.html

Xpad has avoided the use of the hid subsystem for whatever reason, for over a 
decade now. That said, I don't know of any compelling reason to not avoid it. 
But I did it anyways... I made a small usb driver, implemented a stub 
hid_ll_driver, copied the descriptor from TattieBogle... and it works... sort 
of. 

The button layout is obviously different from what we have now and I cannot get 
the D-pad working using a Hat Switch usage or the D-pad usages to save my life. 

I realize that just because other drivers use HID, doesn't mean I should 
although perhaps there's a compelling reason that I'm missing. Is there any 
worth to this work?

What I have is bare bones but works for (incorrectly mapped, using 
TattieBogle's report descriptor) input: https://github.com/computerquip/xpad4

Any feedback would be appreciated.
