Well, I can show you support on my home switch (cabletron) - the network guys
will be a little unhappy if I clear stats on our production network (cisco)
without warning them:

Does having the ability to boot into single user mode break networking? No, it
*allows* you to break networking. Does the _support_ of rmmod break the
kernel? No, but it *allows* you to.

Same thing here. The patch breaks nothing, it provides a tool that if used
without proper understanding, could break things. Just like almost any other
feature in the kernel.
