Because it is intended to help build *protocol graphs*, not *generic
flow parsing*. I.e. only things that lend themselves to be represented
by a graph would work with this - things like conntrack wouldn't. So, I
feel like "graph" is a more accurate name for this, because this is only
for enabling the protocol graph walk, not for full flow parsing.

Yes, it is for drivers. It is not a public API, it is not installed into
public headers. If there is anything I forgot to do to remove it from
being public, please let me know.
