Agreed, that's a fair point. I'm guessing it was inspired by the
ethtool stats? (Which in hindsight were a mistake on my part.)

For the longest time there was no docs or best practices for netlink.
We have the documentation and more infrastructure in place now.
I hope if you wrote the code today the distinction would have been
clearer.

If we start adding APIs for various one-(two?)-offs from the past
we'll never dig ourselves out of the "no idea what's the normal use
of these APIs" hole..
