Try to address #9.

[hober]

This is a strawman fix for #9 to facilitate discussion. It builds on #23, and contains the following changes:

• Defines the role of a proposal champion (like in TC39). Champions are to Proposals as Editors are to Specifications.
• Removes the clause about removing proposals because they lack multi-implementer support.
• Changes how proposals get adopted as specifications. Some new wording, and some ideas from jyasskin/privacycg.github.io
• Removes the clauses about specification feature additions and removals.
• Removes the clause about objecting to an editors' decision solely because it lacks multiple-implementer support
• Removes the definition of implementer.

Overall, looks great. One typo, a couple of optional comments.

I raised some nitpicky points, but essentially, I think this does the right thing and upholds everyone's goals for how this group should operate.

These changes look good!

Can we separate out the change from "Work Item" to "Specification" that are in https://github.com/privacycg/privacycg.github.io/pull/23/files? We can discuss those changes separately.

modulo the comments from @TanviHacks this looks good to me as well

I'll prepare a separate PR for the Work Item version of this, once we've ironed out all of the details here.

[hober]

Okay, I think I've addressed all of the outstanding comments on this.

Please take another, hopefully final, look @cwilso @othermaciej @dbaron @TanviHacks @erik-anderson!

Thanks @hober! The latest changes look good to me. I am okay with splitting out the "Work Item to Specification terminology change" to a separate PR. I will approve this PR after that change is made.

[cwilso]

Thanks @hober! LGTM.

Now that #26 is up, I've merged this into #23.
