1. They did not do the work for DF nor anyone else.
As the slide says, PF is getting harder and harder to port with
increasing version numbers. Probably, due to its tighter integration
with the rest of the OS. But also because it contains unreadable code,
e.g. http://www.netbsd.org/~rmind/pf.txt . On top of these, we have
dfly-specific features, that need to be preserved. So huge-diffs don't
quite work.

2. If you go for the latest/greatest and fail, you end up with your
ancient PF version. But if you do incremental updates, you mitigate
the impact of a potentially unsuccessful port. Also, if you are
tired/bored at some point, others have a stepping-stone to continue
the effort.

You are being touchy and sarcastic, but there's no need for either.

You could have said it at your first email and we wouldn't.
Usually, people that subscribe to a mailing list, choose to receive
messages in a daily digest or so. In such cases, it's reasonable to
CC' them when we reply to their messages.
