Hardly. Its there to handle maintainability issues. Right now its got some
glitches - and the BSD one is a glitch we need to sort out. Clearly BSD
stuff where the source is in the kernel is not harming anyones ability to
deubg.

Well under the DMCA thats probably a criminal offence with five years in
jail. The truth however is that if you want to lie about licensing or run a
modutils that doesn't do it nobody stops you. Its there primarily to deal
with bug filtering from people who don't know better. Folks who know enough
to subvert the mechanism generally also know better than to post Nvdriver
bugs to l/k.
