Is this the only reason you do not support the document? If so I would
be happy to take out the section, if enough people share such a view.
As to your specific complaints, I have addressed both the security model
and the concept of mining centralization on this list in the recent
past. I would like to hear your responses to my claims, if you are
willing to share them. As for positioning DC as a major solution, it is
a little confusing because Luke-Jr and Adam back seem to feel it is at
least worth discussing on those terms (and I know of no reason why it
would not be discussed on those terms). The peer review here on
[bitcoin-dev] seemed to be moving forward without any serious
objections. And it seems unsportsmanlike for you to object, for reasons
which you keep only to yourself.

I don't understand this at all. This document attempts to do exactly
what its predecessor did -- nothing more or less.

No one is suggesting that features be guaranteed, either ever or in
releases.

I really don't think they are related. For a start, software is almost
always delayed. An obvious second is that this entire scaling
conversation is polarized to the hilt and everyone that can be blamed
for something has been blamed for something.
No one likes to be held to a certain deadline, but this roadmap is just
about producing some clarity for people who do not do this 24/7.

I asked Adam Back for it.

Again, I think you're missing the point. If there is a problem with SA,
you can just suggest it be removed from the document.

This is a very strange argument. I would consider it a benefit if people
learned from the document, and discovered things that they had not heard
of before.
There is no "insisting" of any kind.

He probably showed you an earlier draft. But I wrote almost all of this
myself, and I can only recall 2 or 3 phrases (not even complete
sentences) included from Adam Back. And most of the phrases are
themselves just boring descriptions that I'm sure anyone could write.
Some phrases may have simply been taken from bitcoincore.org or
somewhere similar.
I am not exactly sure what you are insinuating but I encourage you to
clarify it.

I really don't understand what you are disclosing. That Adam asked you
for feedback on the draft? And then, in the next sentence, that not
enough experts were asked for feedback on the draft? I'm legitimately
confused by this part.
As I stated, we can remove the drivechain section. But surely you can
appreciate how bizarre your position on roadmaps is. What exactly, did
you intended to create at [1]? Since it is described explicitly as "the
roadmap in Capacity increases for the Bitcoin system", have you been
disagreeing with it's characterization as a 'roadmap' this entire time?
One wonders why you haven't said anything until now.
[1] https://bitcoincore.org/en/2015/12/21/capacity-increase/
In my first email I list the benefits of having a roadmap. One benefit
is that, without one, it is likely that a large majority of outsiders
have almost no idea at all what is being worked on, what effect it will
have, or when it might be ready, or to whom/what they should turn to for
advice on such matters. Do you have a different way of addressing this
communication problem?
Paul
