This is a good compression of similar sentences and simplification of three sections down to two. I believe this change addresses the issue noted in PR #183 and if we merge this PR we can close 183 without prejudice.

Sorry, but I think this makes the text less coherent. We have a paragraph and a list that are both about the goals of this document, that were together as a whole, and now are split far apart. And appending the goals to the existing preamble doesn't flow together, it feels very tacked-on and alien to the rest of the section.

Interesting attempt, but I don't think this works for me.

Moving the first paragraph of the "purpose" section to the abstract might be reasonable, but moving the list part to the intro feels off. If we were to move the list of goals somewhere else, in the extreme, I could see it move to STOD, since it's kind of commentary about the document and so arguably not part of the document itself, but moving it further into the document feels like the opposite of what we should do.

As it stands, I'd be happier with #183 or status quo.

There's no consensus on this PR, and it is unnecessary for an updated Note, so I am labeling it "defer" without prejudice.

I still think this PR is a net improvement, though primarily stylistic, and something we can perhaps more effectively address in the context of feedback we expect from wide review, so I'm leaving it open for now and marking as "Request changes" as a reminder to incorporate any related wide review feedback accordingly.
